Question: What institution did Fukuyama work for the year START II was signed? Passage:In August 1991, hard-line Communists launched a coup against Gorbachev; while the coup quickly fell apart, it broke the remaining power of Gorbachev and the central Soviet government. Later that month, Gorbachev resigned as general secretary of the Communist party, and Russian president Boris Yeltsin ordered the seizure of Soviet property. Gorbachev clung to power as the President of the Soviet Union until December 1991, when the Soviet Union dissolved. Fifteen states emerged from the Soviet Union, and of those states, Russia was the largest and most populous. Bush and Yeltsin met in February 1992, declaring a new era of "friendship and partnership". In January 1993, Bush and Yeltsin agreed to START II, which provided for further nuclear arms reductions on top of the original START treaty. The collapse of the Soviet Union prompted reflections on the future of the world following the end of the Cold War; one political scientist, Francis Fukuyama, speculated that humanity had reached the "end of history" in that liberal, capitalist democracy had permanently triumphed over Communism and fascism. Meanwhile, the collapse of the Soviet Union and other Communist governments led to post-Soviet conflicts in Central Europe, Eastern Europe, Central Asia, and Africa that would continue long after Bush left office.

Question: How long was the reign of the monarch that  ordered a fort to be built at Pill by Royalist forces and completed in 1643? Passage:In April 1603, Martin Pring used the Haven as his departure point for his exploratory voyage to Virginia. The land comprising the site of Milford, the Manor of Hubberston and Pill, was acquired by the Barlow family following the dissolution of the monasteries in the mid-16th century. It acquired an additional strategic importance in the 17th century as a Royalist military base. Charles I ordered a fort to be built at Pill by Royalist forces and completed in 1643 to prevent Parliamentarian forces from landing at Pembroke Castle and to protect Royalist forces landing from Ireland. On 23 February 1644, a Parliamentarian force led by Rowland Laugharne crossed the Haven and landed at Pill. The fort was gunned from both land and water, and a garrison was placed in Steynton church to prevent a Royalist attack from the garrison at Haverfordwest. The fort was eventually surrendered, and quickly taken, along with St Thomas a Becket chapel. Just five years later in 1649 Milford Haven was again the site of Parliamentarian interest when it was chosen as the disembarkation site for Oliver Cromwell's Invasion of Ireland. Cromwell arrived in the Haven on 4 August, meeting George Monck, before Cromwell and over a hundred crafts left for Dublin on 15 August.
