There, she met her husband, Casimir Markievicz - known in Paris as Count Markievicz - an artist whose wealthy Polish family were from Ukraine. They married in London in 1900, with Constance afterwards being known as 'Countess Markievicz'.
They moved to Dublin in 1903, becoming part of artistic and literary worlds.
They mixed with authors, poets, playwrights, artists, painters and more - painting, performing in plays, attending salons and founding organisations. At that time in Ireland, there were growing movements for Ireland to be independent and self-ruling. Cultural movements such as the Gaelic League promoted and preserved Irish language and culture, increased and amplified by political and revolutionary activities.
