Beyond grand ideologies, the conflict was fueled by tangible, everyday grievances. Unionist-controlled councils systematically denied housing to Catholics to maintain political power, creating a flashpoint for the civil rights movement and subsequent violence.

Both loyalist and republican paramilitaries in the 1960s saw themselves as inheritors of an earlier tradition. Groups like the UVF consciously modeled themselves on Sir Edward Carson's 1912 Ulster Volunteers, using this historical precedent to legitimize their violence.

While constitutionally claiming the whole island, Dublin governments showed no real interest in reunification. They even ignored British offers during WWII, fearing the instability of absorbing one million hostile Protestants, a pragmatic stance that contradicted their nationalist rhetoric.

The common narrative that The Troubles erupted suddenly in the 1960s is false. In 1939, the IRA conducted a sabotage campaign with bombings in major English cities, including London and Coventry. This earlier violence is largely erased from British collective memory.

For decades, British politicians viewed the "Irish Question" as solved, leading to a profound lack of interest and oversight. This ignorance allowed systemic discrimination against Catholics in Northern Ireland to continue unchecked within the UK's borders.

Prime Minister Terence O'Neill's efforts to attract foreign investment disrupted traditional Protestant-dominated industries. This economic change, rather than creating harmony, heightened anxieties among working-class Protestants who felt their privileged status was being eroded.

The second Klan, founded in 1915, was by far the largest, with up to five million members. Its power base was not the South but the industrial North and Midwest. While white supremacist, its primary focus was nativist, anti-Semitic, and especially anti-Catholic.

To articulate their identities, both Unionists and Nationalists drew parallels with international conflicts. Unionists saw themselves as a besieged people like Israelis, while Nationalists identified with Palestinians, using these global narratives to legitimize their local grievances.

Major Catholic powers like France and Spain viewed Protestant England much as the modern U.S. might view a hostile nation: a dangerous, ideologically-driven rogue state. They believed Protestantism had shallow roots and that the English population would secretly welcome an intervention to restore Catholicism, thus justifying their plots against Queen Elizabeth.
