However, during the Empire's decline in the 18th century, two factors provoked a kind of feudalism: The cavalrymen were replaced by the tax collectors and local military rulers who were called derebeys ("river lords") or ayan.
Alemdar Mustafa Pasha an ayan in Rusçuk (Ruse, Bulgaria) was supporting the reformist Sultan Selim III (reigned 1789–1807).
Although only four of them showed up, Alemdar and they signed a document called the "Charter of Alliance" (Turkish: Sened’i İttifak)[3] on 29 September 1808.
Overall Magna Carta was a more detailed and developed document geared toward resolving certain power conflicts, especially its first clause guaranteeing the liberty of the English church, and others involving taxation.
Akşin notes some significant differences in Magna Carta like trial by jury not found in the Sened-i İttifak.
