Ira Gershwin was an American lyricist who collaborated with his younger brother, composer George Gershwin, to create some of the most memorable songs in the English language of the 20th century. With George, he wrote more than a dozen Broadway shows, featuring songs such as "I Got Rhythm", "Embraceable You", "The Man I Love", and "Someone to Watch Over Me".

The Provisional Irish Republican Army, officially known as the Irish Republican Army and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent republic encompassing all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an unlawful organisation in the Republic of Ireland, both of whose authority it rejected.
The Real Irish Republican Army, or Real IRA (RIRA), was a dissident Irish republican paramilitary group that aimed to bring about a United Ireland. It was formed in 1997 following a split in the Provisional IRA by dissident members, who rejected the IRA's ceasefire that year. Like the Provisional IRA before it, the Real IRA saw itself as the only rightful successor to the original Irish Republican Army and styled itself as simply "the Irish Republican Army" in English or Óglaigh na hÉireann in Irish. It was an illegal organisation in the Republic of Ireland and designated a proscribed terrorist organisation in the United Kingdom and the United States.
The Troubles were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998.

Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.

Two senior Royal Ulster Constabulary (RUC) officers, Chief Superintendent Harry Breen and Superintendent Bob Buchanan, were shot dead in an ambush by the Provisional IRA South Armagh Brigade. Breen and Buchanan were returning from an informal cross-border security conference in Dundalk with senior Garda officers when Buchanan's car, a red Vauxhall Cavalier, was flagged down and fired upon by six IRA gunmen, who the policemen had taken for British soldiers. Buchanan was killed outright whilst Breen, suffering gunshot wounds, was forced to lie on the ground and shot in the back of the head after he had left the car waving a white handkerchief. They were the highest-ranking RUC officers to be killed during the Troubles.
Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they first used to hunt food, and later to cook.
The following outline is provided as an overview of and topical guide to prehistoric technology.
The New Irish Republican Army, or New IRA, is an Irish republican paramilitary group. It is a continuation of the Real Irish Republican Army, which began to be called the 'New IRA' in July 2012 when Republican Action Against Drugs (RAAD) and other small republican militant groups merged with it.

It is the largest and most active of the "dissident republican" paramilitary groups waging a campaign against the British security forces in Northern Ireland.
