The organisation was founded on 7 February 2024, in response to increased pressures of republicanism among politicians in Grenada following the death of Queen Elizabeth II and the country's Golden Jubilee of independence.

[7] The league condemned suggestions that the oath, as it stood, was to the “British monarch” and that it represented a lack of sovereignty and subordination to the United Kingdom.

It accused prominent proponents of the change of spreading misinformation about the oath and the monarchy, and called on the government to drop any potential plans to amend the constitution.

[13] Other activities include educating and spreading awareness of the constitutional and ceremonial roles of the monarchy in Grenada, and dispelling misconceptions about its position.

Full membership is open and free to all Grenadians both resident in the country and in the diaspora, while non-Grenadians are accepted as honorary members.
