ILanguage issues may have a political dimension, and English has played a major role in this around the world. In this chapter, we look into sociolinguistic aspects involved in politics and nation building, for instance whether English should be adopted to serve in all official functions as a national or official language, or whether a local language, accessible to larger sections of a community, should be adopted instead. We discuss how and to what extent governments should plan and orchestrate language-related activities in education and public discourse, and we look at language policies implemented in the US and Ireland as cases in point. We discuss the impact of governmental bodies on language planning as in the Speak Good English movement in Singapore, and present efforts to achieve language revitalization, which are preeminent considering language obsolescence around the world. The chapter ends with a look at language rights in migrant communities.
