... that during the War of the Keys an army of crusaders fought against the pope? Source: Abulafia (1988), Frederick II, p. 199: "Frederick restored order in Apulia, gathered together local loyalists and newly arrived crusaders, including many trusty Germans, and chased the enemy across country to the other side of Italy." Loud (2016), "The Papal 'Crusade' against Frederick II", p. 92: "as Richard of S. Germano ... described it, ‘the army of the crusaders’ ..., that is Frederick’s forces, fighting against ‘the enemies bearing the sign of the keys’ ... the papal army."
ALT1: ... that according to the Chronicon Wormatiense the Emperor Frederick II would have conquered the entire Holy Land if the pope had not invaded his kingdom while he was away on crusade? Source: Loud (2016), "The Papal 'Crusade' against Frederick II", p. 92: "An annalist from Worms commented, loyally but somewhat hopefully, that if the pope had not launched his invasion of ‘Apulia and Sicily’ then Frederick would have subjected all the Holy Land to himself".
ALT2: ... that in 1229 the city of Piacenza sent 36 knights to assist the pope in the War of the Keys, but 174 knights to help its ally, Bologna, in the battle of San Cesario? Source: Loud (2016), "The Papal 'Crusade' against Frederick II", p. 92: "Piacenza sent 36 knights to assist him. But when in August of that year the Piacenzans sent help to their ally Bologna as its dispute with Modena reached its culmination, they despatched 174 knights."
Comment: The first hook is for the first article only (and the pithiest). The two alts are multi-article hooks. In ALT1, I think "according to the Chronicon Wormatiense" should be between commas, but the system does not like a comma after "that".
Comment: @Srnec: This is a very interesting set of articles! If you prefer the first, do you want to nominate the other two articles as a separate double-nom? That way you could do all 3 articles. BuySomeApples (talk) 07:28, 10 January 2022 (UTC)[reply]
Hook: Hook has been verified by provided inline citation
Cited: - Offline/paywalled citation accepted in good faith
Interesting:
QPQ: Done.
Overall: All of the articles are recent, long enough and sourced. Hooks are cited and interesting (AGF on offline sources). No copyvio detected on Earwig. qpq is not needed, as these will be the nominator's 3rd, 4th and 5th nominations. Since it is a multiple nomination, I am leaning towards ALT1 instead of ALT0 which includes only one of the articles. This one's ready now. BuySomeApples (talk) 05:41, 11 January 2022 (UTC)[reply]
Interesting remark about QPQ... I've been around since 2005. I used to be a prolific DYKer—until they introduced QPQ! According to Wikipedia:List of Wikipedians by number of DYKs, I've got 90, although I have 96 listed on my subpage. I stopped keeping track in 2013, it seems, but I have only a few since then. It didn't even occur to me that you would need more than one review for a multi-page nomination. (Do you?) Srnec (talk) 14:24, 11 January 2022 (UTC)[reply]
