P: The Portuguese Restoration War  was the name given by nineteenth-century Romantic historians to the war between Portugal and Spain that began with the Portuguese revolution of 1640 and ended with the Treaty of Lisbon in 1668. The revolution of 1640 ended the 60-year Iberian Union. The period from 1640 to 1668 was marked by periodic skirmishes between Portugal and Spain, as well as short episodes of more serious warfare, much of it occasioned by Spanish and Portuguese entanglements with non-Iberian powers. Spain was involved in the Thirty Years' War until 1648 and the Franco-Spanish War until 1659, while Portugal was involved in the Dutch-Portuguese War until 1663. In the seventeenth century and afterwards, this period of sporadic conflict was simply known, in Portugal and elsewhere, as the Acclamation War. The war established the House of Braganza as Portugal's new ruling dynasty, replacing the House of Habsburg. This ended the so-called Iberian Union.

P: On December 4, 1920, when the Red Army entered Yerevan, the government of the First Republic of Armenia effectively surrendered. On December 5 the Armenian Revolutionary Committee , made up of mostly Armenians from Azerbaijan, also entered the city. Finally, on the following day, December 6, Felix Dzerzhinsky's dreaded secret police, the Cheka, entered Yerevan, thus effectively ending all existence of the First Republic of Armenia. The Armenian Soviet Socialist Republic was then proclaimed, under the leadership of Gevork Atarbekyan. On February 18, 1921, a national revolt against Bolsheviks started. Gen. Garegin Nzhdeh, commander Garo Sasouni and the last Prime Minister of independent Armenia Simon Vratsyan took the lead of the anti-Bolshevik rebellion and forced out the Bolsheviks from Yerevan and other places. By April the Red Army reconquered most part of Armenia. However, Atarbekyan was dismissed and Aleksandr Miasnikyan, an Armenian high-ranking Red Army commander, replaced him. Garegin Nzhdeh left the Zangezur mountains after the Sovietization of Armenia was finalized in July 1921, leaving Azeri-populated villages cleansed of their population. Persuaded by Soviet leadership, Zangezur had already been ceded by Azerbaijan to Armenia in November 1920 as a "symbol of friendship".
Answer this: Who led the revolt against the Bolsheviks?

A: Gen. Garegin Nzhdeh
