Non parum animus noster

Non parum animus noster (Latin for "Our mind is deeply [troubled]") was a crusading bull issued by Pope Alexander III on either 11 September 1171 or 1172 to promote the Northern Crusades against the pagan Estonians and Finns.

[1][2] It was addressed to the rulers and peoples of Denmark, Sweden and Norway and begins with a description of the threat posed by the Estonians.

[3]Alexander further promised an indulgence and one year's remission of sin to those who fought the pagans.

Those who died in this crusade would receive full indulgence: Trusting God's mercy and merits of the apostles Peter and Paul, we thus concede to those forcefully and magnanimously fighting these often mentioned pagans one year's remission of sins for which they have made confession and received a penance as we are accustomed to grant those who go to the Lord's Sepulchre.

[3]The sole copy of the bull to survive is in Peter Cellensis' letter-book.
