Northern Ireland (direct rule to devolution, no official flag of its own)
Who & why: escalating violence in the conflict known as the Troubles leads the UK government to prorogue the Stormont Parliament in March 1972, imposing direct rule from Westminster; devolved government is restored only intermittently thereafter, most durably after the Good Friday Agreement of April 1998 establishes the Northern Ireland Assembly and a power-sharing executive (itself suspended for various periods since, including 2017–2020 and 2022–2024). Roughly 3,600 people are killed in the Troubles between the late 1960s and the 1998 Agreement, across republican, loyalist, and state actors; this page states that fact neutrally without assigning blame to any single community.
What it represents: Wikipedia and Flags of the World both say the Union Flag is the only official flag for Northern Ireland (FOTW cites the Flags Regulations (Northern Ireland) 2000). The Ulster Banner's official status ended with the abolition of the Northern Ireland government, which Wikipedia places in 1972 in one place and under the Northern Ireland Constitution Act 1973 in another; FOTW treats 1973 as the key date. The March 1972 prorogation and the Troubles figures are not covered by the sources read.
Wikipedia: the Union Flag is the only official flag for Northern Ireland; the government and parliament were abolished in 1972 (elsewhere attributed to the Constitution Act 1973); a 2021 commission recommended a Civic Flag. FOTW: Flags Regulations (Northern Ireland) 2000 restrict flags on government buildings to the Union Flag; College of Arms advised in November 1973 that use of the arms was improper after the 1973 Act.
