History
The Mainlanders are descended from the people who followed Chiang Kai-Shek to Taiwan after the KMT lost the Chinese Civil War. Until the 1970s, Mainlanders controlled the political systems of Taiwan; this generated resentment among benshengren and was one of the main causes of the Taiwan independence movement.
Starting in the 1970s, Mainlander dominance of the government began to recede. This was due to a lack of a political or social theory that would justify continued Mainlander dominance, meritocratic policies which allowed local Taiwanese to move up in the political establishment, and economic prosperity which allowed for social mobility for those outside of the political establishment.
Intermarriage and a new generation raised under the same environment has largely blurred the distinction between waishengren and benshengren.
In the late 1990s, the concept of "The New Taiwanese" became popular both among supporters of Taiwan independence and Chinese reunification in order to emphasize the fact that waishengren are fully Taiwanese. However it quickly became apparent that the notion of New Taiwanese meant different things to supporters of independence and unification. To supporters of independence, the concept of New Taiwanese implied that waishengren would assimilate into a Taiwanese identity which was separate from the Chinese identity. By contrast to supporters of Chinese reunification, the concept implied that all Taiwanese (not just waishengren) which have a strong Taiwanese identity within a larger Chinese identity.
As of the early 21st century, almost all waishengren see themselves as Taiwanese and as socially distinct from current residents of Mainland China, and in contrast to groups such as the Hakka or Taiwanese aboriginals, there has been no effort or interest to develop a distinctive Mainlander identity and most waishengren, especially those of the younger generation, make extensive efforts to establish themselves as Taiwanese. At the same time, part of Taiwanese political discourse is a suspicious by some that waishengren are a fifth column for the People's Republic of China.
People
Prominent Mainlanders in Taiwan include:
Lien Chan sometimes is pejoratively denoted as a Mainlander, although the general perception on Taiwan is that he is not. Although he was born in Mainland China, his father's family had roots in Taiwan.
Recent Mainland Immigration to Taiwan
Since the mid-1990's, there has been a small amount of Mainland immigration into Taiwan. These immigrants are predominantly female and are often colloquially known as dalu xiaomei (大陸小妹), which literally means "little sister from the mainland". These consist of two categories: female brides of businessmen who work in the Mainland; and women who have married rural Taiwanese, mainly through a marriage broker. This population is generally seen as socially distinct from waishengren.
Mainlanders elsewhere
In Tasmania, mainlander refers to Australians from the other five states (or the territories).
In the South Island of New Zealand, mainlander refers to a resident of the South Island, while in the North Island, the opposite applies.
In Canada, mainlander is often used on the East Coast by residents of Newfoundland, Prince Edward Island, or Cape Breton Island. On the West Coast the term is used by people who live on Vancouver Island.
