20 Lira Suleiman II

Süleyman II reigned from 1687 to 1691, ascending the throne after decades of confinement in the kafes — the Ottoman palace prison where princes were isolated to prevent coups. He emerged mentally fragile and largely dependent on the grand vizier Köprülüzade Fazıl Mustafa Pasha, who spent the reign attempting to reverse Ottoman losses following the catastrophic defeat at Vienna in 1683. The Turkish Mint's modern commemorative program has increasingly drawn on lesser-recalled sultans from this post-Vienna contraction period.
