The District of Yamoussoukro is the official political capital and administrative capital city of Côte d'Ivoire, while the economic capital of the country is Abidjan. As of 2010, it was estimated to have 242,744 inhabitants. Located 240 kilometres (150 mi) north-west of Abidjan, the administrative center on the coast, upon rolling hills and plains, the municipality covers 3,500 square kilometres (1,400 sq mi) and is coterminous with the department of the same name. The department and municipality are split into four sub-prefectures: Attiégouakro, Didiévi, Tié-diékro and the Commune of Yamoussoukro. In total, the district contains 169 settlements. In 1998, the city had about 155,803 inhabitants. It is the fourth most populous city in Côte d'Ivoire, after Abidjan, Bouaké, and Daloa. The current governor of the district is Augustin Thiam. Yamoussoukro is pronounced "Yam-So-Kro" by Ivorians. It's possible to hear "Ya-Mu-So-Kro"; the second "U" is silent. Queen Yamousso, the niece of Kouassi N'Go, ran the village of N'Gokro in 1901 at the time of French colonization. The village then comprised 475 inhabitants, and was one of 129 Akoué villages.[citation needed] Diplomatic and commercial relations were then established, but in 1909, on the orders of the Chief of Djamlabo, the Akoué revolted against the administration. Bonzi station, 7 kilometres (4.3 mi) from Yamoussoukro on the Bouaflé road, was set on fire, and the French administrator, Simon Maurice, was spared only by the intervention of Kouassi N'Go. This respected former leader persuaded the Akoué not to wage a war which could only have turned into a disaster. As the situation returned to normal, Simon Maurice, judging that Bonzi had become unsafe, decided to transfer the French military station to Yamoussoukro, where the French Administration built a pyramid to the memory of Kouassi N'Go, Chief of the Akoué. In homage to queen Yamousso, N'Gokro was renamed Yamoussoukro. In 1919, the civil station of Yamoussoukro was removed. Félix Houphouët-Boigny became the leader of the village in 1939. A long period passed wherein Yamoussoukro, still a small agricultural town, remained in the shadows. This continued until after the Second World War, which saw the creation of the African Agricultural Trade Union, as well as the first conferences of its chief. However, it was only with independence that Yamoussoukro finally started to rise. After 1964, the President Félix Houphouët-Boigny made ambitious plans and started to build. One day in 1965, later called the Great Lesson of Yamoussoukro, he visited the plantations with the leaders of the county, inviting them to transpose to their own villages the efforts and agricultural achievements of the region. On 21 July 1977, Houphouët offered his plantations to the State. In March 1983, President Félix Houphouët-Boigny made Yamoussoukro the political and administrative capital of Côte d'Ivoire, as the city was his birthplace. This marked the fourth movement of the country's capital city in a century. Côte d'Ivoire's previous capital cities were Grand-Bassam (1893), Bingerville (1900), and Abidjan (1933). The majority of economic activity still takes place in Abidjan. Yamoussoukro is also the site of what is claimed to be the largest Christian place of worship on Earth: The Basilica of Our Lady of Peace of Yamoussoukro, consecrated by Pope John Paul II on 10 September 1990. Also noteworthy are the Kossou Dam, the Félix Houphouët-Boigny Foundation, the PDCI-RDA House, the various schools of the Félix Houphouët-Boigny National Polytechnic Institute, the international airport (with an average of six hundred passengers and 36 flights in 1995, it is one of two airports in Africa (with Gbadolite) that could accommodate the Concorde), the Town Hall, the Protestant Temple, the Mosque, and the Palace of Hosts. On 6 November 2004, Yamoussoukro Airport was attacked by French infantry after military aircraft from the airport bombed a UN peacekeeper base as well as rebel targets, 9 French peacekeepers and one U.S. civilian were killed. Two Ivorian Sukhoi Su-25 aircraft and several Mil Mi-24 helicopters were destroyed, which was most of the country's air forces. Mobs and rebels tried to attack the French forces after the airport raid. On 30 March 2011, the city of Yamoussoukro fell to forces led by Alassane Ouattara, who had been recognized internationally as president of Côte d'Ivoire.
