Not one of those “special” years, like 175, 150, etc. But today (May 6) is the 176th anniversary of the issuing of the Papal Bulls, establishing the Diocese of Vincennes in 1834.
The establishment was approved on April 12, 1834 and the official bulls were issued on May 6. The Diocese of Vincennes—now the Archdiocese of Indianapolis—was established by Pope Gregory XVI. The territory then comprised the entire state of Indiana and the eastern third of Illinois. The latter was separated from the Diocese of Vincennes upon the establishment of the Diocese of Chicago, November 28, 1843.
