The Mexican president has sent a letter to Spain's King Felipe VI and Pope Francis urging them to apologise for human rights abuses committed during the conquest of the region.
Andrés Manuel López Obrador said the indigenous peoples of Mexico had been the victims of massacres.
In a video filmed at the ruins of an ancient Mexican city , he called for a full account of the abuses.
"The time has come to reconcile. But let us ask forgiveness first," he said.
'The sword and the cross'
Mr López Obrador was unsparing in his criticism of both Spain and the Vatican.
"There were massacres and oppression. The so-called conquest was waged with the sword and the cross," he said.
"They built their churches on top of the (indigenous) temples."
Mexico has the world's second biggest Roman Catholic population, after Brazil.
The government in Madrid responded quickly, firmly rejecting his request for an apology.
"The arrival, 500 years ago, of Spaniards to present Mexican territory cannot be judged in the light of contemporary considerations," Spain said in a statement.
"Our two brother nations have always known how to read our shared past without anger and with a constructive perspective," it added.
