their weapons and swore allegiance to the government. Prem declared the armed struggle over. The army returned to its barracks, and yet another constitution was promulgated, creating an appointed Senate to balance the popularly elected National Assembly. Elections were held in April 1983, giving Prem, now in the guise of a civilian politician, a large majority in the legislature (an arrangement which came to be known as "Premocracy"). Prem was also the beneficiary of the accelerating economic revolution which was sweeping south-east Asia. After the recession of the mid-1970s, economic growth took off. For the first time Thailand became a significant industrial power, and manufactured goods such as computer parts, textiles and footwear overtook rice, rubber and tin as Thailand's leading exports. With the end of the Indochina wars and the insurgency, tourism developed rapidly and became a major earner. The urban population continued to grow rapidly, but overall population growth began to decline, leading to a rise in living standards even in rural areas, although the Isaan continued to lag behind. While Thailand did not grow as fast as the "Four Asian Tigers," (namely Taiwan, South Korea, Hong Kong and Singapore) it achieved sustained growth, reaching an estimated $7100 GDP per capita (PPP) by 1990, approximately double its 1980 average. Prem held office for eight years, surviving another coup in 1985 and two more general elections in 1983 and 1986, and remained personally popular, but the revival of democratic politics led to a demand for a more adventurous leader. In 1988 fresh elections brought former General Chatichai Choonhavan to power. Prem rejected the invitation offered by major political parties for the third term of premiership. Bloody May (1988–1992) By allowing one faction of the military to get rich on government contracts, Chatichai provoked a rival faction, led by Generals Sunthorn Kongsompong, Suchinda Kraprayoon, and other generals of Class 5 of the Chulachomklao Royal Military Academy to stage the 1991 Thai coup d'état in February 1991, charging Chatichai's government as a corrupt regime or 'Buffet Cabinet'. The junta called itself the National Peace Keeping Council. The NPKC brought in a civilian prime minister, Anand Panyarachun, who was still responsible to the military. Anand's anti-corruption and straightforward measures proved popular. Another general election was held in March 1992. The winning coalition appointed coup leader Suchinda Kraprayoon to become Prime Minister, in effect breaking a promise he had made earlier to King
