The city also had a large class of free people of color. By 1860, 3,785 free people of color were in Charleston, nearly 18% of the city's black population, and 8% of the total population. Free people of color were far more likely to be of mixed racial background than slaves. Many were educated, practiced skilled crafts, and some even owned substantial property, including slaves. In 1790, they established the Brown Fellowship Society for mutual aid, initially as a burial society. It continued until 1945.

The UK Energy Research Centre was also established in 2004 and opened its headquarters at Imperial College. In November 2005 the Faculties of Life Sciences and Physical Sciences merged to become the Faculty of Natural Sciences.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The Londre Centre for Nanotechnology was a joint effort between UCL and which college?

In the century after the death of Osman I, Ottoman rule began to extend over the Eastern Mediterranean and the Balkans. Osman's son, Orhan, captured the northwestern Anatolian city of Bursa in 1324, and made it the new capital of the Ottoman state. This Ottoman conquest meant the loss of Byzantine control over northwestern Anatolia. The important city of Thessaloniki was captured from the Venetians in 1387. The Ottoman victory at Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe. The Battle of Nicopolis in 1396, widely regarded as the last large-scale crusade of the Middle Ages, failed to stop the advance of the victorious Ottoman Turks.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which city did Osman's son capture?
Ah, so..
Bursa
