Egypt, Scythia, Persia, and Asia Minor are all described, including a mention of India. The description of Africa as a whole are contentious, with Herodotus describing the land surrounded by a sea. Though he described the Phoenicians as having circumnavigated Africa in the 6th century BC, through much of later European history the Indian Ocean was thought to be an inland sea, the southern part of Africa wrapping around in the south to connect with the eastern part of Asia. This was not completely abandoned by Western cartographers until the circumnavigation of Africa by

used the idea of a sphere to explain how the sun created differing climatic zones based on latitude. This led the Greeks to believe in a division of the world into five regions. At each of the poles was an uncharitably cold region. While extrapolating from the heat of the Sahara it was deduced that the area around the equator was unbearably hot. Between these extreme regions both the northern and southern hemispheres had a temperate belt suitable for human habitation.

of Africa is related by Herodotus and others as having commissioned a successful circumnavigation of Africa by Phoenician sailors. While they were sailing west around the Southern tip of Africa, it was found that the Sun was to their right (the north). This is thought to have been a key trigger in the realization that the Earth is spherical, in the classical world. In the 4th century BC the Greek explorer Pytheas traveled through northeast Europe, and circled the British Isles. He found that the region was considerably more habitable than theory expected, but his discoveries were largely dismissed by his contemporaries because of this. Conquerors also carried out exploration, for example,

was a better border. The relatively narrow habitable band was considered to run from the Atlantic Ocean in the west to an unknown sea somewhere east of India in the east. The southern portion of Africa was unknown, as was the northern portion of Europe and Asia, so it was believed that they were circled by a sea. These areas were generally considered uninhabitable. The size of the Earth was an important question to the Ancient Greeks.

calculated the Earth's circumference with great precision. Since the distance from the Atlantic to India was roughly known, this raised the important question of what was in the vast region east of Asia and to the west of Europe. Crates of Mallus proposed that there were in fact four inhabitable land masses, two in each hemisphere. In Rome a large globe was created depicting this world. Posidonius set out to get a measurement, but his number actually was considerably smaller than the real one, yet it became accepted that the eastern part of Asia was not a huge distance from Europe.

Roman period

While the works of almost all earlier geographers have been lost, many of them are partially known through quotations found in

(64/63 BC – ca. AD 24). Strabo's seventeen volume work of geography is almost completely extant, and is one of the most important sources of information on classical geography. Strabo accepted the narrow band of habitation theory, and rejected the accounts of Hanno and Pytheas as fables. None of Strabo's maps survive, but his detailed descriptions give a clear picture of the status of geographical knowledge of the time.

Ptolemy's '' Geographia'' opens with a theoretical discussion about the nature and techniques of geographical inquiry, and then moves to detailed descriptions of much the known world. Ptolemy lists a huge number of cities, tribes, and sites and places them in the world. It is uncertain what Ptolemy's names correspond to in the modern world, and a vast amount of scholarship has gone into trying to link Ptolemaic descriptions to known locations. It was the Romans who made far more extensive practical use of geography and maps. The Roman transportation system, consisting of of roads, could not have been designed without the use of geographical systems of measurement and

Ancient period

The geographers of ancient India put forward theories regarding the origin of the Earth. They theorized that the Earth was formed by the solidification of gaseous matter and that the Earth's crust is composed of hard rocks (sila), clay (bhumih) and sand (asma). Theories were also propounded to explain earthquakes (bhukamp) and it was assumed that earth, air and water combined to cause earthquakes. The

Early modern period

Following the journeys of

, interest in geography spread throughout Europe. From around c. 1400, the writings of Ptolemy and his successors provided a systematic framework to tie together and portray geographical information. This framework was used by academics for centuries to come, the positives being the lead-up to the geographical enlightenment, however, women and indigenous writings were largely excluded from the discourse. The European global conquests started in the early 15th century with the first Portuguese expeditions to Africa and India, as well as the conquest of America by Spain in 1492 and continued with a series of European naval expeditions across the Atlantic and later the Pacific and Russian expeditions to Siberia until the 18th century.

's world map are prime examples of the new breed of scientific geography. The Waldseemüller map ''Universalis Cosmographia'', created by German cartographer Martin Waldseemüller in April 1507, is the first map of the Americas in which the name "America" is mentioned. Before this, the Native Americans referred to their land depending on their location, with one of the more commonly used terms being "Abya Yala", meaning "land of vital blood". These indigenous geographical discourses were largely ignored or appropriated by the European colonialists to make way for European thought. The Eurocentric map was patterned after a modification of Ptolemy's second projection but expanded to include the Americas.Snyder, John P. (1993). ''Flattening the Earth: 2000 Years of Map Projections'', p. 33. Chicago: The University of Chicago Press. The Waldseemuller Map has been called "America's birth certificate" Waldseemüller also created printed maps called globe gores, that could be cut out and glued to spheres resulting in a globe. This has been debated widely as being dismissive of the extensive Native American history that predated the 16th-century invasion, in the sense that the implication of a "birth certificate" implies a blank history prior.

Imperialism is a crucial concept for the Europeans, as the institution become involved in geographical exploration and colonial project. Authority was questioned, and utility gained its importance.

The natural theology required geography to investigate the world as a grand machine from the Divine.

. The discourse of geographical history gave way to many new thoughts and theories, but the hegemony of the European male academia led to the exclusion of non-western theories, observations and knowledges. One such example is the interaction between humans and nature, with Marxist thought critiquing nature as a commodity within Capitalism, European thought seeing nature as either a romanticised or objective concept differing to human society, and Native American discourse, which saw nature and humans as within one category. The implied hierarchy of knowledge that perpetuated throughout these institutions has only been recently challenged, with the Royal Geographical Society enabling women to join as members in the 20th century.

. Empiricism gains its central place while reflection on it also grew. Practitioners of magic and astrology first embraced and expanded geographical knowledge. Reformation Theology focused more on the providence than the creation as previously. Realistic experience, instead of translated from scripture, emerged as a scientific procedure. Geographical knowledge and method play roles in economic education and administrative application, as part of the Puritan social program. Foreign travels provided content for geographic research and formed theories, such as environmentalism. Cartography showed its practical, theoretical, and artistic value. The concepts of "Space" and "Place" attract attention in geography. Why things are there and not elsewhere is an important topic in Geography, together with debates on space and place. Such insights could date back in 16th and 17th centuries, identified by M. Curry as "Natural Space", "Absolute Space", "Relational Space" (''On Space and Spatial Practice''). After Descartes's ''Principles of Philosophy'', Locke and Leibniz considered space as relative, which has long-term influence on the modern view of space. For Descartes, Grassendi and Newton, place is a portion of "absolution space", which are neural and given. However, according to John Locke, "Our Idea of Place is nothing else, but such a relative Position of any thing" (in ''An Essay Concerning Human Understanding''). "Distance" is the pivot modification of space, because "Space considered barely in length between any two Beings, without considering any thing else between them". Also, the place is "made by Men, for their common use, that by it they might be able to design the particular Position of Things". In the ''Fifth Paper in Reply to Clarke,'' Leibniz stated: "Men fancy places, traces, and space, though these things consist only in the truth of relations and not at all in any absolute reality". Space, as an "order of coexistence", "can only be an ideal thing, containing a certain order, wherein the mind conceives the application of relation". Leibniz moved further for the term "distance" as he discussed it together with "interval" and "situation", not just a measurable character. Leibniz bridged place and space to quality and quantity, by saying "Quantity or magnitude is that in things which can be known only through their simultaneous compresence—or by their simultaneous perception... Quality, on the other hand, is what can be known in things when they are observed singly, without requiring any compresence." In ''Modern Space as Relative'', place and what is in place are integrated. "The Supremacy of Space" is observed by E. Casey when the place is resolved as "position and even point" by Leibniz's rationalism and Locke's empiricism. During the

. Humboldt and Ritter are both regarded as the founders of modern geography as they later established it as an independent scientific discipline. Humboldt is admired as a great geographer, according to D. Livingstone that "modern geography was first and last a synthesizing science and as such, if Goetzmann is to be believed, 'it became the key scientific activity of the age'." In 1789, Humboldt met the geographer George Forster in Mainz, before travellig with him through parts of Western Europe the following year. Forster's travel accounts and writings influenced Humboldt. His ''Geognosia'' including the geography of rocks, animals, and plants is "an important model for modern geography". As a Prussian mining officer, Humboldt founded the Free Royal Mining School at Steben for miners, later regarded the prototype of such institutes. German Naturphilosophie, especially the work of Goethe and Herder, stimulated Humboldt's idea and research of a universal science. In his letter, he made observations while his "attention will never lose sight of the harmony of concurrent forces, the influence of the inanimate world on the animal and vegetable kingdom." His American travel stressed the geography of plants as his focus of science. Meanwhile, Humboldt used empirical method to study the indigenous people in the New World, regarded as a most important work in human geography. In ''Relation historique du Voyage'', Humboldt called these research a new science ''Physique du monde, Theorie de la Terre,'' or ''Geographie physique''. During 1825 to 1859, Humboldt devoted in Kosmos, which is about the knowledge of nature. There are growing works about the New World since then. In the Jeffersonian era, "American geography was born of the geography of America", meaning the knowledge discovery helped form the discipline. Practical knowledge and national pride are main components of the Teleological tradition. Institutions such as the Royal Geographical Society indicate geography as an independent discipline. Mary Somerville's Physical Geography was the "conceptual culmination of ... Baconian ideal of universal integration". According to Francis Bacon, "No natural phenomenon can be adequately studied by itself alone – but, to be understood, it must be considered as it stands connected with all nature."

20th century

In the West during the second half of the 19th and the 20th century, the discipline of geography at various time engaged with four broad themes: environmental determinism, regional geography, the quantitative revolution, and critical geography.

Environmental determinism

Environmental determinism is the theory that a people's physical, mental and moral habits are directly due to the influence of their natural environment. Prominent environmental determinists included

, Ellen Churchill Semple, and Ellsworth Huntington. Environmentally deterministic hypotheses included stereotypes such as "heat makes inhabitants of the tropics lazy" and "frequent changes in barometric pressure make inhabitants of temperate latitudes more intellectually agile." Environmental determinist geographers attempted to make the study of such influences scientific. Around the 1930s, this school of thought was widely repudiated as lacking any basis and being prone to (often bigoted) generalizations. Environmental determinism remains an embarrassment to many contemporary geographers, and leads to skepticism among many of them of claims of environmental influence on culture (such as the theories of

Regional geography

Regional geography was coined by a group of geographers known as possibilists and represented a reaffirmation that the proper topic of geography was study of places (regions). Regional geographers focused on the collection of descriptive information about places, as well as the proper methods for dividing the Earth up into regions. Well-known names from these period are Alfred Hettner in Germany and Paul Vidal de la Blache in France. The philosophical basis of this field in United States was laid out by Richard Hartshorne, who defined geography as a study of areal differentiation, which later led to criticism of this approach as overly descriptive and unscientific. However, the concept of a Regional geography model focused on

has remained incredibly popular amongst students of geography, while less so amongst scholars who are proponents of Critical Geography and reject a Regional geography paradigm. During its heyday in the 1970s through the early 1990s, regional geography made substantive contributions to students' and readers' understanding of foreign cultures and the real world effects of the delineation of borders.

The quantitative revolution

The quantitative revolution in geography began in the 1950s. Geographers formulated geographical theories and subjected the theories to empirical tests, usually using statistical methods (especially hypothesis testing). This quantitative revolution laid the groundwork for the development of

geographic information system A geographic information system (GIS) consists of integrated computer hardware and Geographic information system software, software that store, manage, Spatial analysis, analyze, edit, output, and Cartographic design, visualize Geographic data ...

s. Well-known geographers from this period are Fred K. Schaefer, Waldo Tobler, William Garrison, Peter Haggett, Richard J. Chorley, William Bunge, Edward Augustus Ackerman and Torsten Hägerstrand. An important concept that emerged from this is the first law of geography, proposed by Waldo Tobler, which states that "everything is related to everything else, but near things are more related than distant things."

Critical geography

The term critical geography has been in use since at least 1749, when the book ''Geography reformed: a new system of general geography, according to an Accurate Analysis of the science in four parts'' dedicated a chapter to the topic titled "of Critical Geography." This chapter described critical geography as an approach geographers take to build upon the work of others, and make corrections to their maps based on new information. In the 1970s, the term saw a resurgence as so called "radical geographers" took on the framework of

and poststructuralist theorists to explore the social construction of spatial relations. Critical geography is often viewed as directly opposed to the positive approaches during the 20th century, and quantitative geographers have levied counter criticisms. Some argue the rise in critical geography was in response to the difficulty in understanding the new techniques and technology, and that the early criticisms of these technologies critical geographers put forth in the 20th century have been addressed by advances in computers. Critical geography has been called " anti-science."

21st century

Social theory/spatial analysis split

After an initial debate on the merits of positivism, where critical geographers attempted "to excise everything that went before in quantitative geography" and "overthrow the dominant quantitative approach" during the 1960s and 1970s, by 1995, GIS practitioners and quantitative geographers began to "decline comment" to critical geography in an academic context. While quantitative geographers and critical geographers continued to work together in some context, a lack of "common vocabulary," and rounds of "polarizing debates," lead to a situation of "mutual indifference and absence of dialog between the two groups" during the 2000s. The result of this split led to the creation of two camps within human geography that many view as irreconcilable, described by geographer Mei-Po Kwan as the "social-cultural geographies" and the "spatial-analytical geographies."
