Jannisaries (sp)? Weren’t they eunuchs?
No.The Janiassarie Corps was composed of Christian youth from the Balkans taken by the Ottomans as a form of tax. They were raised as wards of the Sultan and trained to be professional soldiers.
Eunuchs were used by the Ottomans in political and governing roles by the Ottomans, and were often a power behind the throne kind of deal, like their counterparts in the various chinese dynasties. But they were not part of the Janissarie Corps. which eventually, like the Praetorian Guard and the Roman Legions, got into the business of choosing [or trying to] new Sultans.
