Here is a question about this article: Popes called for crusades to take place elsewhere besides the Holy Land: in Spain, southern France, and along the Baltic. The Spanish crusades became fused with the Reconquista of Spain from the Muslims. Although the Templars and Hospitallers took part in the Spanish crusades, similar Spanish military religious orders were founded, most of which had become part of the two main orders of Calatrava and Santiago by the beginning of the 12th century. Northern Europe also remained outside Christian influence until the 11th century or later, and became a crusading venue as part of the Northern Crusades of the 12th to 14th centuries. These crusades also spawned a military order, the Order of the Sword Brothers. Another order, the Teutonic Knights, although originally founded in the crusader states, focused much of its activity in the Baltic after 1225, and in 1309 moved its headquarters to Marienburg in Prussia.
What is the answer to this question: In what century did the Northern Crusades begin?
****
So... 12th

Here is a question about this article: London's bus network is one of the largest in the world, running 24 hours a day, with about 8,500 buses, more than 700 bus routes and around 19,500 bus stops.

Here is a question about this article: Nicholas began courting Britain by means of conversations with the British ambassador, George Hamilton Seymour, in January and February 1853.:105 Nicholas insisted that he no longer wished to expand Imperial Russia:105 but that he had an obligation to the Christian communities in the Ottoman Empire.:105 The Tsar next dispatched a highly abrasive diplomat, Prince Menshikov, on a special mission to the Ottoman Sublime Porte in February 1853. By previous treaties, the sultan was committed "to protect the (Eastern Orthodox) Christian religion and its churches." Menshikov demanded a Russian protectorate over all 12 million Orthodox Christians in the Empire, with control of the Orthodox Church's hierarchy. A compromise was reached regarding Orthodox access to the Holy Land, but the Sultan, strongly supported by the British ambassador, rejected the more sweeping demands.
What is the answer to this question: In what year was Prince Menshikov sent to the Ottoman Sublime Porte?

So...
1853
