Crusade bull
indulgences allowed to the inhabitants of the Iberian kingdoms

A crusade bull or crusading bull (Latin: bulla cruciata) was a papal bull that granted privileges, including indulgences, to those who took part in the Crusades against infidels. A bull is an official document issued by a pope and sealed with a leaden bulla. All crusade bulls were written in Latin. Those launching a new general crusade were encyclicals addressed to all the archbishops of the Latin Church.
Bulls were not the only means by which popes organized crusades. Many types of papal letters without the bulla attached were issued to arrange, guide and direct crusading efforts. The bulls issued for the Reconquista ('reconquest') in the Iberian Peninsula evolved into something distinct. By the modern period, the "bull of the crusade" (Spanish: bula de la cruzada, Portuguese: bula da cruzada) was used by Spanish and Portuguese monarchs as a means of raising money through donations for various projects, not necessarily military. This system was finally abolished in 1966.
Early privileges
Privileges for just wars against infidels have a long history before the first formal crusade bull.

Why this record matters
“Crusade bull” is worth following because a concise public description often conceals a longer documentary argument. Here, Crusade, bull and indulgences provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 3, 2025. The linked authority identifier is Q4259833. The first chronological checks are 1966.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
