The history of the Croatian Sisters of Charity of saint Vincent de Paul on our soil starts in 19th century when in 1845 the first group of six sisters, invited by the then bishop of Zagreb Juraj Haulik, arrived from Zams and Innsbruck in Austria in Zagreb, and there they have started their activities. The beginnings were blessed by fruitful activities in the spirit of the Vincentian charisma. Soon, the native daughters started to join in. The historical circumstances and the increase in the number of vocations led to the legal independence of that young community in 1856. Since then, the Congregation has been an independent community of the Sisters of Charity. All baptised are missionaries by the power of the sacrament of Baptism. Consecrated people are missionaries even more directly and intensively. Missionary activity should first come to life in the person’s surroundings. Then, its fruitfulness in proclaiming the Gospel around the world will be more efficient. That is what has happened with the Croatian Congregation of the Sisters of Charity. Apart from the fruitful activities in Croatia, the sisters have expanded their activities on the area of the former Ottoman Empire, then in South America, and more recently on the faraway Solomon Islands in the Pacific. In this work the missionary work of sister Slava Vedrina has been singled out. Sr. Slava lived in South America for 68 years, and in Paraguay, due to her work among the poorest, she was called the Paraguayan Mother Teresa. The native sisters have continued to proclaim the Good News after her death in 2002.
