When was the rosary first made?

The rosary, as a form of prayer, is believed to have developed in the Middle Ages, with its origins tracing back to the 12th century. The practice of using beads to count prayers likely began with the use of the Paternoster beads, which helped the faithful keep track of their prayers. By the 15th century, the rosary as we know it today, specifically the repetition of the Hail Mary and the structure of the decades, became more formalized under the influence of the Dominican Order.
