This investigation focused on social meanings in being converted to Christianity of the Hmong as well as the roles ofChristianization on their new identity in the urban society in Chiang Mai. The investigation applied the concepts of identity, modernization and social network as the study framework. The study was conducted at the Blue Church under the Christian and Missions Alliance to explain such a social phenomenon. This work indicated that the change from animism to Christianity of the Hmong was due to various factors. They included an escape from complicated and costly social structures and rituals, patriarchal society, and beliefs that were not in line with and accepted by modern society.
            As a consequence, Christianity was a choice that the Hmong used to raise their status to look modernized. That is, they were open for Western belief and lifestyle through the space of the Blue Church or Hmong Christian Church. The church thus played a significant role in transferring knowledge and organizing weekly activities and annual festivals in order to cultivate their awareness on and know God as well as to create groups among church members and extend their network to proselytize Christianity in Chiang Mai. However, converting to Christianity did not diminish their ethnicity, but enabled them to maintain their identity by using their ethnic language more at the church. Their traditional dress did not contradict their religious belief, making their ethnic identity and their religious belief to become well assimilated. Furthermore, the conversion provided them an opportunity and confidence to adapt to a new society. They were also able to redefine themselves and to become fluid in their socialization in the urban environment.
