As established in the Colombian Constitution of 1991, women in Colombia have the right to bodily integrity and autonomy; to vote (see also: Elections in Colombia); to hold public office; to work; to fair wages or equal pay; to own property; to receive an education; to serve in the military in certain duties, but are excluded from combat arms units; to enter into legal contracts; and to have marital, parental and religious rights. Women's rights in Colombia have been gradually developing since the early 20th Century.[5]
