Love poetry in this era was typically about courtly and unrequited love. According to Pilkington, the development of courtly love "may perhaps have been the greatest change in Western culture between the fall of Rome and the rise of the Renaissance."
Courtly love put women on pedestals and glorified amorous passion in a way that was anathema both to Classical civilization and Christian salvation.
While this may seem unexpected given women's disadvantage relative to men in the Middle Ages, one could argue that deifying a woman obliterates her and is therefore another kind of objectification.
Love poetry often alluded to the courtship of a woman as a battlefield for men, the surrender of the female and the victory of the male in winning his female prize through heroic acts.
Courtly love evolved over the centuries until by Shakespeare's time it was romantic love and a prelude to marriage.
