Bandaranaike attempted to reform the former British Colony of Ceylon into a socialist republic by nationalising organisations in the banking, education, industry, media and trade sectors. Changing the administrative language from English to Sinhala, she exacerbated discontent among the native Tamil population, and with the estate Tamils, who had become stateless under the Citizenship Act of 1948. During Bandaranaike's first two terms as Prime Minister, the country was plagued by high inflation and taxes, a dependence on food imports to feed the populace, high unemployment, and polarisation between the Sinhalese and Tamil populations because of her Sinhalese nationalist policies. Surviving an attempted coup d'état in 1962, as well as a 1971 insurrection of radical youths, in 1972 she oversaw the drafting of a new constitution and the formation of the Sri Lankan republic. In 1975, Bandaranaike created what would eventually become the Sri Lankan Ministry of Women and Child Affairs, also appointing the first woman to serve in the Sri Lankan Cabinet. Bandaranaike's tenure was marked by inadequate economic development at the national level. She played a large role abroad as a negotiator and a leader among the Non-Aligned Nations.
