The Buddhist movement was the first large-scale missionary movement in the history of world religions. Chinese missionaries were able to assimilate Buddhism, to an extent, to native Chinese Daoists, which brought the two beliefs together. Buddha's community of followers, the Sangha, consisted of male and female monks and laity. These people moved through India and beyond to spread the ideas of Buddha. As the number of members within the Sangha increased, it became costly so that only the larger cities were able to afford having the Buddha and his disciples visit. It is believed that under the control of the Kushans, Buddhism was spread to China and other parts of Asia from the middle of the first century to the middle of the third century. Extensive contacts started in the 2nd century, probably as a consequence of the expansion of the Kushan empire into the Chinese territory of the Tarim Basin, due to the missionary efforts of a great number of Buddhist monks to Chinese lands. The first missionaries and translators of Buddhists scriptures into Chinese were either Parthian, Kushan, Sogdian, or Kuchean.
