of slavery. On March 22, 1873, the Spanish government approved what became known as the Moret Law, which provided for gradual abolition. This edict granted freedom to slaves over 60 years of age, those belonging to the state, and children born to slaves after September 17, 1868. The Moret Law established the Central Slave Registrar. In 1872 it began gathering the following data on the island's slave population: name, country of origin, present residence, names of parents, sex, marital status, trade, age, physical description, and master's name. This has been an invaluable resource for historians and genealogists. Abolition of slavery On March 22, 1873, slavery was abolished in Puerto Rico, but with one significant caveat. The slaves were not emancipated; they had to buy their own freedom, at whatever price was set by their last masters. The law required that the former slaves work for another three years for their former masters, other people interested in their services, or for the state in order to pay some compensation. The former slaves earned money in a variety of ways: some by trades, for instance as shoemakers, or laundering clothes, or by selling the produce they were allowed to grow, in the small patches of land allotted to them by their former masters. In a sense, they resembled the black sharecroppers of the southern United States after the American Civil War, but the latter did not own their land. They simply farmed another's land, for a share of the crops raised. The government created the Protector's Office which was in charge of overseeing the transition. The Protector's Office was to pay any difference owed to the former master once the initial contract expired. The majority of the freed slaves continued to work for their former masters, but as free people, receiving wages for their labor. If the former slave decided not to work for his former master, the Protectors Office would pay the former master 23% of the former slave's estimated value, as a form of compensation. The freed slaves became integrated into Puerto Rico's society. Racism has existed in Puerto Rico, but it is not considered to be as severe as other places in the New World, possibly because of the following factors: In the 8th century, nearly all of Spain was conquered (711–718), by the Arab-Berber/African Moors who had crossed over from North Africa. The first African slaves were brought
