[2] In the aftermath of the First World War, the League of Nations granted Britain a mandate over several territories in the Middle East, including the area that would become Jordan.

Both the current monarch, King Abdullah II, and his son, Hussein, Crown Prince of Jordan, were educated at the Royal Military Academy Sandhurst in England.

King Abdullah II was educated at St Edmund's School in England, was commissioned as a second lieutenant in the British Army and served a year in Britain and West Germany as a troop commander in the 13th/18th Royal Hussars, and studied at Pembroke College at the University of Oxford.

[4] The sudden revolt led by the Hashemite family, while not be able to secure total support from other Arab tribes, played an instrumental role on the collapse of Ottoman rule in Jordan.

[9] During the Arab–Israeli War of 1948, Britain secretly favored a total Jordanian invasion of West Bank hoping to wipe out the possible creation of a Palestinian state led by Amin al-Husseini.

[10][11] Britain also secretly supported Israeli jets to fly in Jordan when Syria sent troops to invade the country, forcing the Syrians to retreat.

These factors combined in such a way that the administration of Margaret Thatcher and the Jordanian government under King Hussein of Jordan began coordinating with one another and cooperating with one another on a wide variety of issues.

[17][18] In August 2019, King Abdullah II visited Prime Minister Boris Johnson in London to discuss economic co-operation.

[19] Prime Minister Johnson expressed the UK's commitment to working with Jordan on issues as far ranging as the economy, COVID-19 and combatting terrorism.

These exercises involve the British Army's 16 Air Assault Brigade and Jordan's Quick Reaction Force, enhancing interoperability and operational readiness in challenging environments.

British special forces have worked alongside Jordanian counterparts in various regional operations, highlighting the strategic importance of their alliance.

This cooperation is reinforced by high-level visits and ongoing dialogue between military leaders from both nations, aiming to address shared security threats and enhance regional defense capabilities.

[26] Co-operation has continued during the Israel-Hamas war since the 7 October 2023 Hamas attack on Israel, in order to provide humanitarian aid to Gazan civilians and secure the stability of the Jordanian government.
