Has Buddhism been statist for a long time?

Again, as was also the case in so many Buddhist countries, the success of Buddhism relied heavily on its connections to the court.  In Korea, the tradition of “state protection Buddhism” was inherited from China.  Here, monarchs would build and support monasteries and temples, where monks would perform rituals and chant sutras intended to both secure the well-being of the royal family, in this life and the next, and protect the kingdom from danger, especially foreign invasion.

…As in China, the Korean sangha remained under the control of the state; offerings to monasteries could only be made with the approval of the throne; men could only become monks on “ordination platforms” approved by the throne; and an examination system was established that placed monks in the state bureaucracy.  As in other Buddhist lands, monks were not those who had renounced the world but were vassals of the king, with monks sometimes dispatched to China by royal decree.  With strong royal patronage, Buddhism continued to thrive through the Koryo period (935-1392), with monasteries being granted their own lands and serfs, accumulating great wealth in the process.

That is an excerpt from Donald S. Lopez, Jr. Buddhism: A Journey through History, an excellent book.  Maybe the best book on the history of Buddhism I have read?  And one of the very best books of this year.
