[EX Q]: Question: When did Ventspils stop being a part of the Russian Empire? Passage:Spāde was born into a fisherman's family in Ventspils, then part of the Russian Empire, in 1891. He was trained as a mechanical engineer at the Riga Polytechnic Institute, which he graduated in 1914. He was drafted in the Imperial Russian Baltic Fleet at the outset of World War I. He advanced from a position of michman to that of a torpedo boat commander and ended up as a commanding officer at the Black Sea Navy Brigade Headquarters in Batumi, where he married a Georgian woman in 1917. After the fall of the Russian Empire, he joined the navy of the People's Republic of Ukraine in early 1918 and, following a peace treaty between Ukraine and the Central Powers, pledged his loyalty to the Democratic Republic of Georgia. In Georgian service Spāde commanded a detachment of cutters in Batumi. In June 1918, the Ottoman troops took control of Batumi and made the town's garrison, including Spāde, captive. Released in October 1918, Spāde joined the ranks of the Armed Forces of South Russia, a White party to the Russian Civil War. He was promoted to Senior Lieutenant and put in charge of the Sevastopol port. In March 1920, Spāde, together with the defeated White forces, was evacuated to Constantinople, where he accepted Latvian citizenship and returned to Latvia with his wife.
