Dear readers, Catholic Online was de-platformed by Shopify for our pro-life beliefs. They shut down our Catholic Online, Catholic Online School, Prayer Candles, and Catholic Online Learning Resources essential faith tools serving over 1.4 million students and millions of families worldwide. Our founders, now in their 70's, just gave their entire life savings to protect this mission. But fewer than 2% of readers donate. If everyone gave just $5, the cost of a coffee, we could rebuild stronger and keep Catholic education free for all. Stand with us in faith. Thank you.Help Now >

Shop Leo IV
A Roman with Lombard heritage, St. Leo IV was a Benedictine before his election to the papal throne in 847. He was crowned without imperial consent and without imperial distress. He fortified Rome against the Saracens, who had sacked the city the previous year. In 849, he formed an alliance with several Greek cities. The allegiance defeated the Saracens near Ostia. Leo excommunicated Anastasius the Librarian who had mysteriously abandoned the church in 850, the year that Leo crowned Lothair and his son Louis II co-emperors. Leo's interest in church music was steady throughout his career. Leo died in 855.
