Saint Salomone Leclercq (15 November 1745 – 2 September 1792) – born Guillaume-Nicolas-Louis Leclercq – was a French Roman Catholic professed religious who was killed during the French Revolution for his refusal to swear an oath of allegiance to the new government.
Leclercq assumed the religious name of "Salomone" after he was admitted as a professed member of the De La Salle Brothers.Leclercq was killed in 1792 after he refused to take the oath of allegiance to the new French government almost two weeks before the kingdom was dissolved.
He was killed in the garden of a Carmelite convent around a fortnight after he had been arrested and imprisoned in Paris.His beatification received the approval of Pope Pius XI who beatified Leclercq and his 190 companions on 17 October 1926 while Pope Francis approved his canonization in 2016.
A date for sanctification was fixed at a gathering of cardinals on 20 June 2016 and the canonization was celebrated on 16 October 2016.
