Exile to Siberia
While being transported in a prisoners' convoy to Siberia, Piłsudski was held for several weeks at a prison in
Irkutsk. During his stay, another inmate insulted a guard and refused to apologize; Piłsudski and other political prisoners were beaten by the guards for their defiance and Piłsudski lost two teeth. He took part in a subsequent hunger strike until the authorities reinstated political prisoners' privileges that had been suspended after the incident. For his involvement, he was sentenced in 1888 to six months' imprisonment. He had to spend the first night of his incarceration in 40-degree-below-zero Siberian cold; this led to an illness that nearly killed him and health problems that would plague him throughout life.
During his exile, Piłsudski met many ''
Sybiraks'', groups of people who have resettled to Siberia. He was allowed to work in an occupation of his choosing and tutored local children in mathematics and foreign languages (he knew French, German and Lithuanian in addition to Russian and his native Polish; he would later learn English).

Creation of an armed resistance
At the beginning of the 1900s, almost all parties in Russian Poland and Lithuania took a conciliatory position toward the Russian Empire and aimed at negotiating within it a limited autonomy for Poland. Piłsudski's PPS was the only political force prepared to fight the Empire for Polish independence and to resort to violence to achieve that goal.

The Japanese offered Piłsudski much less than he hoped; he received Japan's help in purchasing weapons and ammunition for the PPS and their combat organisation, and the Japanese declined the Legion proposal.
In the fall of 1904, Piłsudski formed a paramilitary unit (the
Combat Organization of the Polish Socialist Party, or ''bojówki'') aiming to create an armed

. In early 1905 he ordered the PPS to launch a general strike there; it involved some 400,000 workers and lasted two months until it was broken by the Russian authorities. In June 1905, Piłsudski sent paramilitary aid to an uprising in Łódź, later called
June Days. In Łódź, armed clashes broke out between Piłsudski's paramilitaries and gunmen loyal to Dmowski and his
National Democrats. On 22 December 1905, Piłsudski called for all Polish workers to rise up; the call went largely unheeded.
Piłsudski instructed the PPS to boycott the elections to the
First Duma. The decision, and his resolve to try to win Polish independence through revolution, caused tensions within the PPS, and in November 1906, the party fractured over Piłsudski's leadership. His faction came to be called the "Old Faction" or "Revolutionary Faction" ("''Starzy''" or "''
Frakcja Rewolucyjna''"), while their opponents were known as the "Young Faction", "Moderate Faction" or "Left Wing" ("''Młodzi''", "''Frakcja Umiarkowana''", "''
Lewica''"). The "Young" sympathized with the
Social Democrats of the Kingdom of Poland and Lithuania, and believed priority should be given to co-operation with Russian revolutionaries in toppling the tsarist regime and creating a socialist

By 1909, his faction was the majority in the PPS, and Piłsudski remained an important PPS leader until the outbreak of the First World War.
Preparation for WWI
Piłsudski anticipated a coming European war with the need to organize the leadership of a future Polish Army. He wanted to secure Poland's independence from the three empires that partitioned Poland out of political existence in the late 18th century. In 1906 Piłsudski, with the connivance of the Austrian authorities, founded a military school in

for the training of paramilitary units. In 1906 alone, the 800-strong paramilitaries, operating in five-man teams in Congress Poland, killed 336 Russian officials; in subsequent years, the number of their casualties declined, and the paramilitaries' numbers increased to some 2,000 in 1908. The paramilitaries also held up Russian currency transports that were leaving Polish territories. On the night of 26/27 September 1908, they robbed a Russian mail train that was carrying tax revenues from Warsaw to Saint Petersburg. Piłsudski, who took part in this

First policies
Piłsudski set about organizing a Polish army out of Polish veterans of the German, Russian, and Austrian armies. Much of former Russian Poland had been destroyed in the war, and systematic looting by the Germans had reduced the region's wealth by at least 10%. A British diplomat who visited Warsaw in January 1919 reported: "I have nowhere seen anything like the evidence of extreme poverty and wretchedness that meet one's eye at almost every turn."

described Piłsudski as very deliberate in his decision-making: Piłsudski collected all available pertinent information, then took his time weighing it before arriving at a final decision. He held long working hours, and maintained a simple lifestyle, eating plain meals alone at an inexpensive restaurant. Though he was popular with much of the Polish public, his reputation as a loner (the result of many years' underground work) and as a man who distrusted almost everyone led to strained relations with other Polish politicians.
Piłsudski and the first Polish government were distrusted in the West because he had co-operated with the Central Powers from 1914 to 1917 and because the governments of Daszyński and Moraczewski were primarily socialist. It was not until January 1919, when pianist and composer

. Piłsudski's plan met with opposition from most of the prospective member states, which refused to relinquish their independence, as well as the Allied powers, who thought it to be too bold a change to the existing
balance-of-power structure. According to historian
George Sanford, it was around 1920 that Piłsudski came to realize the infeasibility of that version of his Intermarium project. Instead of a Central and Eastern European alliance, there soon appeared a series of border conflicts, including the

, there was unrest on all Polish borders. Regarding Poland's future frontiers, Piłsudski said: "All that we can gain in the west depends on the Entente—on the extent to which it may wish to squeeze Germany." The situation was different in the east, of which Piłsudski said that "there are doors that open and close, and it depends on who forces them open and how far." In the east, Polish forces clashed with Ukrainian forces in the Polish–Ukrainian War, and Piłsudski's first orders as Commander-in-Chief of the Polish Army, on 12 November 1918, were to provide support for the
Polish struggle in Lviv.
Piłsudski was aware that the Bolsheviks would not ally with an independent Poland and predicted that war with them was inevitable. He viewed their advance west as a major problem, but he also considered the Bolsheviks less dangerous for Poland than their
White opponents.
