Like any ruling, some did, some didn't. From anAn article atcited by the OP brings up a couple of possible groups which may have complied with this, The MilitaryHistoryNowHoly Roman Empire under (emphasis mine):Conrad III and the region referred to as Flanders. So we can look at the extent of any ranged weapon bans in those locations.
But while the church frowned on Christian-on-Christian use of the crossbow, religious authorities of the day had no problem when the weapons were being pointed at non-believers, heretics and heathens. As such, the weapons featured prominently in Crusader armies. Yet back in Europe, they were controversial. Both the Holy Roman Emperor Conrad III and the Kingdom of Flanders abided by the holy ban in European wars and sent their own crossbow men packing; other continental powers skirted the rules when they could. But even with their prohibition, crossbows continued to be widely used.
- Conrad III
AnotherThis source, International Encyclopedia of Military History edited by James C. Bradford, while discussing crossbows, confirms the information that Conrad III, Holy(Holy Roman Emperor from 1138-1152),
condemned their use in his domains.
So it appears that Conrad made some attempt at abiding by the Popes wishes (at least concerning the use of crossbows),but was only was able to uphold this ban for 13 years, and then resumed using the use of crossbows as well. No information here concerning the inclusion or not of long bows in this , and this article,as most that I found, seems to also interpret the papal ruling as mainly directed at crossbows.
- Flanders
Concerning Flanders, which was another area mentioned as banning ranged weapons, this ban is brought up in the book Archery and Crossbow Guilds in Medieval Flanders, 1300-1500 By Laura Crombie. In this text,it states:
It later mentions that shooting outside the city walls was allowed, so it seems this was not a ban on the use of these weapons in war such as canon 29 seems to indicate, but just local ordinances to make it safer in the city limits. (The presence of archery and crossbow related guilds there would also seem to agree that military use was still allowed). So the above Flanders reference, though it did actually specifically include bows, seems to have little relation to the ban from the Second Council of the Lateran.
So some (thesources indicate that the Holy Roman Empire under Conrad III, who(who took power in 1138) did try to follow the ruling (which was in in April 1139), thoughit was for only a limited time at best, whilewhile others (apparently everyone else) 'skirted the rules'. Most information I find seems to be treating this as a crossbow ban, andregardless of our interpretation of the actual text of the Canon. (I have seen several sources listing it as slingers and archers). I have not found any mention of inclusionan actual ban of longthe use of bows (beside the later Flemish cities reference) in this ban, as of yet.
