When the Kshatriya was defeated it was the duty of the other
classes to join the Kshatriya to protect the country, a call that
even Brahmins and Sanyasins took up in former times. This helped
India resist many foreign invaders. However there came a tendency to
blame the Kshatriya instead, which was only to give up the fight
altogether, and inhibit the Kshatriya from rising again.
A related factor was the degeneration of caste into clan
alliances, which made the country easy to manipulate under a divide
and conquer strategy. A fragmented society can be easily dominated
by a united outside force. The same thing happened to Native
American groups, who, divided by tribal alliances, were easily
conquered by the Europeans by placing one tribe against another.
Such old clan conflicts are often more deep seated than the problems
imposed by a new invader.
The
same foreign invaders would eventually turn against the clans who
had allied with them once their help was no longer necessary. Yet
whatever the social complications that aided the decline of the
Kshatriya, a spiritual and religious attitude against the Kshatriya
arose that made it appear that a Kshatriya Dharma was opposed to the
fundamental principles of Hinduism, which were of a spiritual nature
only.
