Be specific bro ? One funny incident in history was this situation In the old Orthodox Christan kingdoms. One time this king sent solider to subjugate the emir of harere and on the day of the battle this skilled and cunning general from the emir's military rank chose the day of Sunday to attack because Orthodox Christan contingent were susperstious on Sunday to go to war or do anything. Beacuse the in the past most of the popes that come to govern the church (which was also influential in government and most of the orthdox Christian's were very devout ) made alot of days in the weekend holy days where people don't partake in work or war anything for that matter so in that day that cunning general attacked and won the battle and the emir stayed in power for the time being 😁.
