Castling consists of moving the king two squares towards a rook, then placing the rook on the other side of the king, adjacent to it. Castling is only permissible if all of the following conditions hold:{{sfn|FIDE|2023|loc=article 3.8.2}}
* The king and rook involved in castling must not have previously moved;
* There must be no pieces between the king and the rook;
* The king may not currently be under attack, nor may the king pass through or end up in a square that is under attack by an enemy piece (though the rook is permitted to be under attack and to pass over an attacked square);
* The castling rook must be on the same rank as the king

An unmoved king and an unmoved rook of the same color on the same rank are said to have ''castling rights''.{{sfn|FIDE|2023|loc=article 3.8.2.1}}
