question: In the latter half of the 16th century, the Sultanate of Demak, the dominant power in the island of Java, disintegrated into several independent states. At the turn of the 17th century, three of these states emerged as the leading powers: the Sultanate of Banten in western Java, the Sultanate of Mataram in inland central Java, and the Duchy of Surabaya in coastal eastern Java. Mataram consolidated its power by absorbing other principalities: Pajang in c. 1588, Demak , Madiun  and Kediri . Following Mataram's unsuccessful westward expedition against Banten in about 1597, Mataram turned its expansion eastward, into areas under the influence of Surabaya. The Duchy of Surabaya was centered roughly in today's city of Surabaya in the northern coast of eastern Java. It was a wealthy and powerful state, and the city was an important port in the trade route between Malacca and the Spice Islands., The city was approximately 37 kilometres  in circumference, and was fortified by canals and cannons. Allied with the nearby state of Pasuruan, the Duchy expanded its influence throughout the eastern part of Java in the beginning of the 17th century. By 1622, it was in control of Gresik and Sedayu in eastern Java. It was also the overlord of Sukadana and Banjarmasin in southern Borneo. More doubtful reports said it might have also extended its influence to Pasuruan, Blambangan, the Brantas valley region, and Wirasaba. Other than these, Surabaya was also allied with Tuban, Malang, Kediri, Lasem, all in eastern Java, as well as Madura off the northern coast. This alliance was primarily a response to the growing power of Mataram, and Surabaya was the founder and the most powerful member.
Answer this question: How many years after Mataram consolidated its power by absorbing other principalities did Mataram turn it's expansion eastward?
answer: 9

question: The Basmachi movement  or Basmachi Revolt was an uprising against Russian Imperial and Soviet rule by the Muslim peoples of Central Asia. The movement's roots lay in the anti-conscription violence of 1916 that erupted when the Russian Empire began to draft Muslims for army service during World War I. In the months following the October 1917 Revolution the Bolsheviks seized power in many parts of the Russian Empire and the Russian Civil War began. Turkestani Muslim political movements attempted to form an autonomous government in the city of Kokand, in the Fergana Valley. The Bolsheviks launched an assault on Kokand in February 1918 and carried out a general massacre of up to 25,000 people. The massacre rallied support to the Basmachi movements who waged a guerrilla and conventional war that seized control of large parts of the Fergana Valley and much of Turkestan. The fortunes of the decentralized movement fluctuated throughout the early 1920s but by 1923 the Red Army's extensive campaigns had dealt the Basmachis many defeats. After major Red Army campaigns and concessions regarding economic and Islamic practices in the mid-1920s, the military fortunes and popular support of the Basmachi declined. Resistance to Russian rule and Soviet leadership did flare up again, to a lesser extent, in response to collectivization campaigns in the pre-WWII era.
