===Early history===
The Menapii Celtic tribe are specifically named on [[Ptolemy]]'s 150 AD map of Ireland, where they located their first colony – Menapia – on the Leinster coast {{Circa|216 BC}}. They later settled around Lough Erne, becoming known as the Fir Manach, and giving their name to Fermanagh and Monaghan.{{citation needed|date=May 2018}} [[Mongán mac Fiachnai]], a 7th-century King of Ulster, is the protagonist of several legends linking him with [[Manannan mac Lir]]. They spread across Ireland, evolving into historic Irish (also Scottish and Manx) clans.

The [[Battle of Clontibret]], fought between the forces of [[Hugh O'Neill, Earl of Tyrone|The Earl of Tyrone]], ''An Ó Néill'' (The O'Neill), of [[Tír Eoghain]], and the [[English Crown]], was fought in northern County Monaghan in May 1595. The territory of Monaghan had earlier been wrested from the control of the [[McMahon clans|MacMahon]] sept in 1591, when the leader of the MacMahons was hanged by authority of the Dublin government; this was one of the events that led to the [[Nine Years War (Ireland)|Nine Years War]] and the [[Tudor conquest of Ireland]].
