Rabbi Nachman of Horodenka was a Hasidic leader
A disciple of the Baal Shem Tov.
Rabbi Nachman of Haradanka was a descendant of the famous Maharal of Prague. He was a close disciple of the Baal Shem Tov. Rabbi Simcha, the son of Rabbi Nachman married the righteous Marat Feiga, the grand daughter of the Baal
Shem Tov, and the sister of Rabbi Moshe Chaim Efraim of Sadilkov and Rabbi Baruch of Medzibosh. Rabbi Simcha was the father of Rabbi Nachman of Breslov.
The Baal Shem Tov loved and admired Rabbi Nachman of Haradanka very much. Rabbi Pinchas of Koritz, another disciple of The Baal Shem Tov, praised him a lot for being a great holy man and claimed that as long as Rabbi Nachman was in Poland, the Russians were not able to enter Poland and fight them. On the day that Rabbi Nachman left for a trip to Israel, the Russians entered Poland.
Rabbi Nachman of Haradanka was known for his powerful prayers and strong, "like iron" Emunah (belief in God).
A testimony to his greatness was Rabbi Elazar Rokach who went to live in Israel. One of his major goals was to meet Rabbi Nachman of Haradanka in Israel. Rabbi Elazar's hope was that together with Rabbi Nachman, he could hasten the Redemption. However, upon his arrival in Israel Rabbi Elazar discovered that Rabbi Nachman had recently returned back to Europe. When Rabbi Nachman heard of Rabbi Elazar's arrival in Israel, he hurried back to Israel. But by the time Rabbi Nachman made it back to Israel, Rabbi Elazar had already passed away from the world.
May the merit of the tzaddik Rabbi Nachman of Haradanka protect us all, Amen!
