He wrote to Pope Innocent XII professing submission to the Roman Catholic Church, for which shortly after Nahabed was expelled from Etchmiadzin by a bishop.
This Bishop Stephen planned a coup and deposed the Catholicos, putting himself on the throne and reigning for 10 months, at which point the Armenian clergy seized him and restored Nahabed.
Pope Innocent responded to the letter in 1696 with the gift of a papal throne, which is still on display in Etchmiadzin today.
When Nahabed died there was still much confusion and turmoil amongst the people, and so the pontificate stayed vacant for more than a year until Alexander of Julfa was called to the throne by general consent.
