question: Uros III's decision not to attack the Byzantines after the victory at the Battle of Velbazhd against Bulgaria resulted in the alienation of many nobles, who sought to expand to the south. By January or February 1331, Dusan was quarreling with his father, perhaps pressured by the nobility. According to contemporary pro-Dusan sources, evil advisors turned Uros III against his son; he decided to seize and exclude Dusan of his inheritance. Uros III sent an army into Zeta against his son, the army ravaged Skadar, but Dusan had crossed the Bojana. A brief period of anarchy in parts of Serbia took place before the father and son concluded peace in April 1331. Three months later, Uros III ordered Dusan to meet him. Dusan feared for his life and his advisors persuaded him to resist, so Dusan marched from Skadar to Nerodimlje, where he besieged his father. Uros III fled, and Dusan captured the treasury and family. He then pursued his father, catching up with him at Petric. On 21 August 1331, Uros III surrendered, and on the advice or insistence of Dusan's advisors, he was imprisoned. Dusan was crowned King of All Serbian and Maritime lands in the first week of September. The civil war had prevented Serbia from aiding Ivan Stephen and Anna Neda in Bulgaria, who were deposed in March 1331, taking refuge in the mountains. Ivan Alexander of Bulgaria feared for the danger of Serbia as the situation there had settled, and immediately sought peace with Dusan. As Dusan wanted to move against richer Byzantium, the two made peace and an alliance in December 1331, accepting Ivan Alexander as ruler. It was sealed with the marriage of Dusan and Helena, the sister of Ivan Alexander.

question: With Upper Burma securely under his control, Nyaungyan's successor Anaukpetlun marched south. His 14,000-strong land and naval forces sacked Prome on 13 July 1608 after a bloody siege of eight months. His 12,000-strong forces then attacked Toungoo, then ruled by his cousin, Natshinnaung, in August 1610. After a siege of 23 days, Natshinnaung agreed to become a vassal on 4 September 1610. But Natshinnaung was deeply unhappy with his reduced status, and secretly invited de Brito of Syriam to attack Toungoo. In July 1612, Syriam and Martaban forces ransacked the city for ten days, and left, taking Natshinnaung to Syriam. In response, Anaukpetlun's army of 13,000 left Ava for Syriam on 26 December 1612. A flotilla of 80 war boats and 30 cargo boats was also sent down the Irrawaddy to blockade the port. The Burmese forces overcame Portuguese outer defences, and finally blockaded the port on 24 February 1613. But Portuguese gunners and musketeers kept the Burmese at bay for 34 days while waiting for reinforcements from Goa to arrive. On 29 March 1613, however, the Burmese successfully brought down a section of the walls, from their tunnels below. The city was sacked. On 7 April 1613, de Brito his son and Natshinnaung were all executed by impalement. A month later, on 14 May 1613, Binnya Dala of Martaban, submitted. The ruler was nominally tributary to Siam but had ruled the region like a sovereign since the death of Naresuan in 1605. Alarmed, the Siamese sent an army to Ye, south of Martaban, to prevent the Burmese from marching down the coast. But the Siamese did not try to retake Martaban.
Answer this question: Who did Anaukpetlun replace?
answer: Nyaungyan

question: On 17 December 1297, the three brothers overthrew Kyawswa, and founded the Myinsaing Kingdom. At Pagan, Kyawswa's son Sawhnit was elected king by the dowager Queen Saw but soon became a governor under the authority of Myinsaing. Another of Kyawswa's sons, Kumara Kassapa, escaped to China. The Mongols did not know about the dethronement until June-July 1298. In 1300, the Myinsaing forces led by Athinkhaya attacked the Mongol garrisons north of Mandalay named Nga Singu and Male. On 22 June 1300, the Mongol Emperor declared that Kumara Kassapa was the rightful king of Burma, and sent in an army from Yunnan. The invasion force reached Myinsaing on 25 January 1301 but could not break through. The besiegers took the bribes by the three brothers, and withdrew on 6 April 1301. The Mongol government at Yunnan executed their commanders but sent no more invasions. They withdrew entirely from Upper Burma starting on 4 April 1303. By then, the city of Pagan, once home to 200,000 people, had been reduced to a small town, never to regain its preeminence. The brothers placed one of Kyawswa's sons as the governor of Pagan. Anawrahta's line continued to rule Pagan as governors under Myinsaing, Pinya and Ava kingdoms until 1369. The male side of Pagan ended there although the female side passed into Pinya and Ava royalty. But the Pagan line continued to be claimed by successive Burmese dynasties down to the last Burmese dynasty Konbaung.
Answer this question: How many Mongol garrisons did Myinsaing forces attack in 1300?

2
