Mubarak acted quickly to bribe the Ottoman bureaucracy through lavish gift giving in order to gain support for his appointment as kaymakam [sub governor] of Kuwait like his previous brothers.

Jaber Al-Mubarak Al-Hamad Al-Sabah came two weeks after all the ministers submitted their resignations to Sabah after several cabinet members, including the prime minister himself, were questioned by MPs.
