List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 206 listed states can be divided into three categories based on membership within the United Nations System: 193 UN member states, 2 UN General Assembly non-member observer states, and 11 other states. The ''sovereignty dispute'' column indicates states having undisputed sovereignty (188 states, of which there are 187 UN member states and 1 UN General Assembly non-member observer state), states having disputed sovereignty (16 states, of which there are 6 UN member states, 1 UN General Assembly non-member observer state, and 9 de facto states), and states having a special political status (2 states, both in free association with New Zealand). Compiling a list such as this can be a complicated and controversial process, as there is no definition that is binding on all the members of the community of nations concerni ...

Tehran
Tehran (; fa, تهران ) is the largest city in Tehran Province and the capital of Iran. With a population of around 9 million in the city and around 16 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, and has the second-largest metropolitan area in the Middle East, after Cairo. It is ranked 24th in the world by metropolitan area population. In the Classical era, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city destroyed in the medieval Arab, Turkic, and Mongol invasions. Modern Ray is an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786, because of its proximity to Iran's territories in the Caucasus, then separated from Iran in the Russo-Iranian Wars, to avoid the vying factions of the previously ruling Iranian dynasties. The capital has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply ...

Veresk Bridge
The Veresk bridge ( fa, پل ورسک) is a masonry arch bridge in northern Iran. It was constructed by Impresa G. R. Pizzagalli & C. from Italy from 1934 to 1935 by leadership of the Italian engineer Cesare Delleani, during the reign of Reza Shah. It is located in the Veresk district of Savadkuh County, in Mazandaran province. History In 1933 the Danish Consortium Kampsax, which had been chosen by the government of Iran as general contractor for the Trans-Iranian Railway, assigned Lot number 8 on the Northern section of the project to the Italian Engineer Guido Romeo Pizzagalli from Milan. In November 1933 he founded the company Impresa G.R. Pizzagalli & C. together with several Italian engineers, among them the three brothers Battista, Guido and Cesare Delleani from Biella. The lot had a total length of 7,600 m with a height difference of 186 m and was composed of 10 tunnels, and two major bridges, one with a length of 52 m and an arch of 25 m and the second with a leng ...

Nizari Ismaili State
The Nizari state (the Alamut state) was a Shia Nizari Ismaili state founded by Hassan-i Sabbah after he took control of the Alamut Castle in 1090 AD, which marked the beginning of an era of Ismailism known as the "Alamut period". Their people were also known as the ''Assassins'' or ''Hashashins''. The state consisted of a nexus of strongholds throughout Persia and Syria, with their territories being surrounded by huge swathes of hostile territory. It was formed as a result of a religious and political movement of the minority Nizari sect supported by the anti-Seljuk population. Being heavily outnumbered, the Nizaris resisted adversaries by employing strategic, self-sufficient fortresses and the use of unconventional tactics, notably assassination of important adversaries and psychological warfare. Despite being occupied with survival in their hostile environment, the Ismailis in this period developed a sophisticated outlook and literary tradition. Almost two centuries after ...

Citadel
A citadel is the core fortified area of a town or city. It may be a castle, fortress, or fortified center. The term is a diminutive of "city", meaning "little city", because it is a smaller part of the city of which it is the defensive core. In a fortification with bastions, the citadel is the strongest part of the system, sometimes well inside the outer walls and bastions, but often forming part of the outer wall for the sake of economy. It is positioned to be the last line of defence, should the enemy breach the other components of the fortification system. The functions of the police and the army, as well as the army barracks were developed in the citadel. History 3300–1300 BC Some of the oldest known structures which have served as citadels were built by the Indus Valley civilisation, where citadels represented a centralised authority. Citadels in Indus Valley were almost 12 meters tall. The purpose of these structures, however, remains debated. Though the structures foun ...

Concentric Castle
A concentric castle is a castle with two or more concentric curtain walls, such that the outer wall is lower than the inner and can be defended from it. The layout was square (at Belvoir and Beaumaris) where the terrain permitted, or an irregular polygon (at Krak and Margat) where curtain walls of a spur castle followed the contours of a hill. Concentric castles resemble one castle nested inside the other, thus creating an inner and outer ward. They are typically built without a central free-standing keep. Where the castle includes a particularly strong tower (donjon), such as at Krak or Margat, it projects from the inner enceinte. Development Surrounding fortresses or towns with a series of defensive walls where the outer walls are lower than the inner walls is something that has been found in fortifications going back thousands of years to cultures like the Assyrians, Persians, Ancient Egyptians and Babylonians. The ancient city of Lachish, a place in Israel, was ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

( chg, ''Temür'', 'Iron'; 9 April 133617–19 February 1405), later Timūr Gurkānī ( chg, ''Temür Küregen''), was a Turco-Mongol conqueror who founded the Timurid Empire in and around modern-day Afghanistan, Iran, and Central Asia, becoming the first ruler of the Timurid dynasty. An undefeated commander, he is widely regarded as one of the greatest military leaders and tacticians in history, as well as one of the most brutal. Timur is also considered a great patron of art and architecture as he interacted with intellectuals such as Ibn Khaldun, Hafez, and Hafiz-i Abru and his reign introduced the Timurid Renaissance. Born into the Barlas confederation in Transoxiana (in modern-day Uzbekistan) on 9 April 1336, Timur gained control of the western Chagatai Khanate by 1370. From that base, he led military campaigns across Western, South, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alborz Mountains
The Alborz ( fa, البرز) range, also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the smaller Aladagh Mountains and borders in the northeast on the parallel mountain ridge Kopet Dag in the northern parts of Khorasan. All these mountains are part of the much larger Alpide belt. This mountain range is divided into the Western, Central, and Eastern Alborz Mountains. The Western Alborz Range (usually called the Talysh) runs south-southeastward almost along the western coast of the Caspian Sea. The Central Alborz (the Alborz Mountains in the strictest sense) runs from west to east along the entire southern coast of the Caspian Sea, while the Eastern Alborz Range runs in a northeasterly direction, toward the northern parts of the Khorasan region, southeast of the Caspian Sea.
