Slavery or serfdom is one of the most interesting features in the social life of the Siamese. It is another of those customs which they have borrowed from a neighbouring nation. The Shan ancestors of the Siamese were "free" men, and the name "Thai", which was the name they called themselves, signified that fact. It is, moreover, the name of the nation to-day, though the condition of slavery is a very wide-spread one. For many years the inhabitants of the plains were tributary to Cambodia, whose princes and nobles treated all servants and aliens as slaves. When the foreign yoke was thrown off, this domestic custom was instituted amongst the "free" men, and all the subjects of the king became theoretically his slaves. But as he was unable to find employment for this large body of serfs, he delegated a portion of his ownership to persons of lower rank. These in turn handed on their powers to other people, and so arose a condition of universal serfdom, which, however, was only strictly enforced in the case of the poorer classes. The system thus organised divided the whole nation into a series of social strata, but the limits between the different grades of society have never been so rigid and impassable as the adamantine boundaries that separate the castes of India. In fact, the serf in Siam to-day may be a nobleman of high rank in the future, should he possess ability of sufficient distinction to warrant so great a promotion. Until the present reign there were theoretically no "free" men in the kingdom at all, for everybody owed homage to some one of higher degree; but one of the first acts of H. M. King Chulalongkorn after he came to the throne, was to issue a decree by which all children born of slaves were thereafter declared free. As freedom could be purchased there were also many people in the land who had obtained their independence. Though the king's decree struck a very decisive blow at the condition of domestic slavery, a system of state slavery still prevails inasmuch as the laws relating to _corvée_ and conscription are still enforced. Chinese, priests, and foreigners are all exempt from enforced labour of any kind, but the first-named of these classes has to pay a triennial tax as the price of its exemption. The people who are now in bondage are in that condition chiefly as the result of financial indebtedness.
