Mohammad Nadir Shah

Mohammad Nadir Shah seized the throne after the fall of Habibullah Kalakani. He led forces from the Eastern Province to capture Kabul, ending the nine-month rule of the bandit king and restoring the Musahiban branch of the Barakzai dynasty to power.

Nadir Shah's forces crushed a rebellion in the Khost province led by loyalists of the deposed Amanullah Khan. The rebellion was defeated after several months of fighting, consolidating Nadir Shah's control over the country and eliminating a major challenge to his rule.

Nadir Shah introduced a new constitution for Afghanistan, establishing a constitutional monarchy with a parliament. The constitution granted limited civil liberties and established a bicameral legislature, though real power remained with the king. It replaced the 1923 constitution of Amanullah Khan.

Mohammad Nadir Shah was shot and killed by Abdul Khaliq Hazara, a student at a Kabul school, during a prize distribution ceremony. The assassination was motivated by personal grievances and political tensions, leading to the accession of his son Mohammad Zahir Shah.
