Why did William wilberforce resign from parliament?

William Wilberforce resigned from Parliament in 1812 primarily due to health concerns and personal reasons, including a desire to focus on his philanthropic efforts and the abolition of the slave trade. He had been a prominent advocate for social reform and the abolition movement, but the toll of years of intense political struggle affected his well-being. After stepping down, he continued to be actively involved in social causes, though outside of parliamentary duties.
