Saint Theresa of Portugal, also known as Tarasia and Teresa, was born on 4 October 1178 in Coimbra, Portugal. She was the oldest daughter of King Sancho I and was born into a life of royalty. As a princess, Theresa enjoyed a privileged upbringing and received a proper education. In her youth, Theresa married King Alfonso IX of Leon, Spain. As part of her dowry, northern Portugal became part of their marital possessions. Theresa and Alfonso had three children together, but their marriage faced a significant obstacle when it was revealed that they were cousins. Upon this discovery, the Vatican dissolved their union. After her marriage ended, Theresa returned to Portugal and decided to devote herself to a life of spirituality and service. She embarked on a mission to convert the Benedictine monastery at Lorvão into a convent for 300 Cistercian nuns. Although she did not take religious vows herself initially, Theresa chose to reside in the convent and oversee its transformation. In 1231, Theresa temporarily left the convent to settle a bitter succession dispute between her own children over the throne of Leon. Her efforts resulted in a peaceful resolution, and once her children found reconciliation, she returned to the Lorvão convent. At this point, Theresa decided to take religious vows, dedicating her life entirely to serving God as a nun. For the remainder of her life, Theresa lived in the Lorvão Abbey, fully embracing her life as a Cistercian nun. She actively participated in the spiritual practices of the order, engaging in prayer, contemplation, and acts of charity. Her unwavering devotion to her faith and her commitment to peace and resolution made her a beloved figure within the community. Saint Theresa of Portugal passed away on 18 June 1250 at Lorvão Abbey, Portugal, due to natural causes. Her life and contributions left a lasting impact on the religious community. She was recognized for her exemplary life, and on 20 May 1705, Pope Clement XI canonized her as a saint, confirming her cultus. Although there is no specific patronage associated with Saint Theresa of Portugal, her life of devotion and her role in reconciling her own family can serve as inspiration for those facing familial conflicts or seeking spiritual guidance. Her feast day is celebrated on 17 June each year, commemorating her life and her significant contributions to the Cistercian order and the broader Catholic faith.
