Q: Following a series of invasions beginning shortly after their conquest of England in 1066, the Normans seized much of Wales and established quasi-independent Marcher lordships, owing allegiance to the English crown. However, Welsh principalities such as Gwynedd, Powys and Deheubarth survived and from the end of the 11th century, the Welsh began pushing back the Norman advance. Over the following century the Welsh recovery fluctuated and the English kings, notably Henry II, several times sought to conquer or establish suzerainty over the native Welsh principalities. Nevertheless, by the end of the 12th century the Marcher lordships were reduced to the south and south east of the country. The principality of Gwynedd was the dominant power in Wales in the first half of the 13th century, with Powys and Deheubarth becoming tributary states. Gwynedd's princes now assumed the title "Prince of Wales". But war with England in 1241 and 1245, followed by a dynastic dispute in the succession to the throne, weakened Gwynedd and allowed Henry III to seize Perfeddwlad . However, from 1256 a resurgent Gwynedd under Llywelyn ap Gruffudd resumed the war with Henry and took back Perfeddwlad. By the Treaty of Montgomery of 1267, peace was restored and, in return for doing homage to the English king, Llywelyn was recognised as Prince of Wales and his re-conquest of Perfeddwlad was accepted by Henry. However, sporadic warfare between Llywelyn and some of the Marcher Lords, such as Gilbert de Clare, Roger Mortimer and Humphrey de Bohun continued.
How many Welsh principalities survived the Norman advance and began pushing back on it in the 11th century?
A: 3

Q: In 1922, the Bolsheviks closed down the Novodevichy Convent and turned it into the Museum of Women's Emancipation. By 1926, the monastery had been transformed into a history and art museum. In 1934, it became affiliated with the State Historical Museum. Most of its facilities were turned into apartments, which spared the convent from destruction. In 1943, when Stalin started to make advances to the Russian Orthodox Church during World War II, he sanctioned opening the Moscow Theological Courses at the convent. Next year the program was transformed and became the Moscow Theological Institute. In 1945, the Soviets returned Assumption Cathedral to the believers. The residence of the Metropolitan of Krutitsy and Kolomna has been located in the Novodevichy Convent since 1980. In 1994, nuns returned to the convent, which is currently under the authority of the Metropolitan of Krutitsy and Kolomna. Some of the churches and other monastic buildings are still affiliated with the State Historical Museum. In 1995, religious services resumed in the convent on patron saint's days.
How many years after the convent was closed down did nuns return to it?
A:
72
