قابوس بن سعيد
In 1970, Qaboos bin Said al Said ousted his father, Sa'id bin Taimur, in the 1970 Omani coup d'état who later died in exile in London. Al Said ruled as sultan until his death. The new sultan confronted insurgency in a country plagued by endemic disease, illiteracy, and poverty. One of the new sultan's first measures was to abolish many of his father's harsh restrictions, which had caused thousands of Omanis to leave the country, and to offer amnesty to opponents of the previous régime, many of whom returned to Oman. 1970 also brought the abolition of slavery.
