into the centralised Siamese state in King Chulalongkorn's reign, the old local nobility had been allowed to grab large tracts of land. The end result was that by the 1960s close to 30% of the households were landless. In the early 1970s university students helped to bring some of the local protests on to the national stage. The protests focused on land loss, high rents, the heavy-handed role of the police, corruption among the bureaucracy and the local elites, poor infrastructure, and overwhelming poverty. The government agreed to establish a committee to hear peasant grief. Within a short time the committee was flooded with more than 50,000 petitions, more than it could possibly handle. Officials called many of the peasants' demands unrealistic and too far-reaching. Political environment The political environment of Thailand changed little during the mid-1960s. Thanom and his chief deputy Praphas maintained a tight grip on power. The alliance between these two was further cemented by the marriage of Praphas's daughter to Thanom's son Narong. By the late 1960s, however, more elements in Thai society had become openly critical of the military government which was seen as being increasingly incapable of dealing with the country's problems. It was not only the student activists, but also the business community that had begun to question the leadership of the government as well as its relationship with the United States. Thanom came under increasing pressure to loosen his grip on power when the king commented that it was time for parliament to be restored and a new constitution put into effect. After Sarit had suspended the constitution in 1958, a committee was established to write a new one, but almost ten years later, it had still not been completed. Finally, in 1968 the government issued a new constitution and scheduled elections for the following year. The government party founded by the military junta won the election and Thanom remained prime minister. Surprisingly, the assembly was not totally tame. A number of MPs (mostly professionals such as doctors, lawyers, and journalists) began to openly challenge some of the government's policies, producing evidence of widespread government corruption on a number of large projects. As a new budget was being debated in 1971, it actually appeared that the military's demand for more funds might be voted down. Rather than suffer such a loss of face, Thanom carried out a putsch against his own government,
