All the Macedonian converts to Muhammedan faith speak Serb language, and have preserved many of the Serb customs

MACEDONIA AND THE MACEDONIAN POPULATION.

The Serb element in the Central and Western Macedonia is mixed with other non-Slav nations — Albanians, Turks, Greeks and Arumuns.

There are also many, and distributed throughout all the countrj-, the so-called Muhadjirs (the emigrants) from Serbia, Bulgaria, Bosnia, Hertsegovina and Montenegro. Amongst the Serbs in Macedonia live also former Christians converted to Islam. Those of Kichevo call themselves Apovtsi, and those of Tikvesh call themselves Turks.

The Muhammedan Serbs under the leadership of Hussein Bey

THE SULTAN REIGNS IN BOSNIA

There was not in the other Southern Slav lands much consolation for the National party. In Bosnia the French Revolution and the Serbian wars of independence had an unfortunate effect, for in 1831 the Muhammedan Serbs of that province, under the leadership of Hussein Bey, the captain of Gradačac, began a holy war against the „giaour Sultan,“ because Mahmud thought it timely to promulgate a few reforms.

Hussein assumed the title of  „The Dragon of Bosnia„; and if it had not been for several other Moslem potentates who were not only inimical to the Sultan but to the Dragon and to each other, it would have taken the Sultan’s army more than five years to assert itself. In 1839 the Sultan’s epresentative at Gulhane had orders to reform the administration, and this time the chief of the indignant begs was Ali Pasha Rizvanbegović, a powerful personage in Herzegovina.

The revolt was, after a good deal of bloodshed, suppressed by Omar Pasha, who was determined to break once and for all the arrogance of the Bosnian aristocracy.

Hundreds of begs were executed, drowned in the Bosna or taken in chains to Constantinople. But all these transactions did nothing to improve the lot of the raia. They had been roundly told in 1832 by His Apostolic Majesty that any one of those Christians „who persist in venturing to raise the banner of revolt“ would be sent back from the Imperial and Royal frontier.  After all there was a courtesy which monarchs must maintain towards each other.
