In the early nineteenth century, many Russian artists, officers and nobles were sent into exile to Siberia for their part in the Decembrist revolt against Tsar Nicholas I. Irkutsk became the major center of intellectual and social life for these exiles, and much of the city's cultural heritage comes from them; also, many of their wooden houses, adorned with ornate, hand-carved decorations, survive today in stark contrast with the standard Soviet apartment blocks that surround them. The wide streets and ornate, continental architecture led to Irkutsk being called the "Paris of Siberia", although travelers are unlikely to have a difficult time distinguishing the two today.
During the civil war that broke out after the Bolshevik Revolution, Irkutsk became the site of many furious, bloody clashes between the "Whites" and the "Reds" aka Bolsheviks, and a number of city landmarks remain from that era. In 1920, Kolchak, the once-feared commander of the largest contingent of anti-Bolshevik forces, was executed there, effectively destroying the anti-Bolshevik resistance.
Today, Irkutsk is one of the biggest cities in Siberia, with a growing population of more than 590,000 people. It's home to several universities and a major branch of the Russian Academy of Sciences, thanks to its proximity to Lake Baikal.
