Besparalik - Mahmud I Kostantiniyye mint

The besparalik — literally "five paras" — emerged as a practical response to chronic small-change shortages that plagued Ottoman commerce throughout the early eighteenth century. Mahmud I came to power in 1730 following the Patrona Halil rebellion, a violent janissary-led revolt that deposed Ahmed III and briefly placed real power in the hands of a former Albanian sailor. The new sultan's early coinage reforms were as much about reasserting imperial financial credibility as meeting transactional need.

Kostantiniyye issues of this type were struck in billon at a fineness that reflected ongoing debasement pressures rather than any single policy decision.
