The current king, Hamad bin Isa Al Khalifa, has been in power since 1999, following the death of his father, Isa bin Salman Al Khalifa. The Al-Khalifa family has played a significant role in Bahrain's political landscape, overseeing various reforms and developments. The family has faced challenges, including political unrest and demands for greater democratic reforms, particularly during the Arab Spring in 2011.
