European leaders convened at the Congress of Vienna in 1815 to discuss the post-Napoleonic War aftermath, which is a noteworthy example of this. Many of the delegates played friendly card games with their counterparts during official negotiataur satta kingions, which gave them a chance to rapport and gain trust. These unofficial meetings were instrumental in determining how the Congress turned out and ultimately brought about a period of comparatively calm conditions in Europe. Apart from diplomacy, royal families have also employed card games as a way to settle disputes. High-stakes card games were occasionally used to resolve territorial or succession disputes, with the victor obtaining control of the contested lands or titles.
