Little is known about the Matis specifically before the 1970s, but they were likely affected along with other indigenous tribes of the area, by the depredations associated with the
Amazon rubber booms of the late nineteenth and twentieth centuries.
"First Contact" Period The Matis people were contacted by the Brazilian agency
FUNAI during 1976–1978, although it was not until two years later in 1978 that FUNAI employees began visiting the then-five Matis villages. As a result of this initial contact, a large number (likely between 1/3 and 2/3) of the Matis population, devoid of natural
immunity, died from diseases and from lack of care. By 1983, only 87 Matis people survived, down from a population of initially 300 or more people. The decade also saw the loss of three of their villages which now, completely abandoned, are occasionally visited by the Matis to harvest fruit trees. Many cultural practices also fell by the wayside, including coming-of-age tattooing practices, but some of these practices have seen a resurgence since the 1990s. ==Current relationship with broader Brazilian society==
