got its first tram-line, and the city's first electric lights were installed in the city center. Between 1903 and 1907, the area was one of the least healthy in Europe, with a mortality rate of 33.6 for every 1000 persons. Untreated sewage spilled into the river, causing several cholera epidemics between 1907 and 1910. Although the region had an active Sanitary Executive Commission that sent out instructions on the best ways to prevent outbreaks and dispatched a delegate from the Anti-Plague Commission to Tsaritsyn in 1907, local municipal officials did not put any precautions into place, citing economic considerations. The city's drinking water came directly from the river, the intake pipe dangerously close to both the port and the sewage drain. There were neither funds nor political will to close the port (the main hub of economic activity) or move the intake pipes. As a result, in the three years spanning 1908 to 1910, Tsaritsyn lost 1,045 people to cholera. With a population of only 102,452 at the time, that amounts to a staggering 1.01% loss of the population. Between 1908 and 1911, Tsaritsyn was home to Sergei Trufanov, also known as the 'mad monk' Iliodor. He spent most of his time causing infighting and power struggles within the Russian Orthodox Church, fomenting anti-semitic zeal and violence in local populations, attacking the press, denouncing local municipal officials and causing unrest wherever he went. The most permanent mark he left on the city was the Holy Spirit Monastery (), built in 1909, parts of which still stand today. In light of the explosive population growth, the lack of political action on sanitation and housing, the multiple epidemics and the presence of volatile personalities, it is no surprise that the lower Volga region was a hotbed of revolutionary activity and civil unrest. The inability of the Tsarist government to provide basic protections from cholera on the one hand and subjecting the populace to strict but ineffective health measures on the other, caused multiple riots in 1829, in the 1890's and throughout the first decade of the 1900s, setting the stage for multiple Russian revolutions and adding fuel to the political fire. During the Russian Civil War of 1917–1923, Tsaritsyn came under Soviet control from November 1917. In 1918 White Movement troops under Pyotr Krasnov, the Ataman of the Don Cossack Host, besieged Tsaritsyn. The Reds repulsed three assaults by the Whites. However,
