After the death of the Puzzle King, Komar was almost destroyed during the resulting Jigsaw Civil War until the two siblings decided to share rulership and became the Silver Monarch and the Golden Queen. Seeing the political fights before, during, and even after the war ended set the king down a path in an attempt to bridge the gulf between himself and his sister.
One of those attempts with the On the Young Journeys Mandate which was an attempt to break up the primarily rural areas of the country and have them interact with others that didn't share the same political, religions, or cultural beliefs.
The mandate, dismissively accepted by the queen and viewed as a fluff mandate by the Copper Council, added a lengthy journey across the country as an additional requirement before citizenship was granted. The minimum, the journey must be at least a hundred leagues, take no less than two weeks, and cannot involve visiting any association within three degrees of relationship. That means visits to grandparents or second cousins can't be considered.
Originally, the king wanted five degrees of relationship but the queen resisted and it was reduced.
Implementation
Among rich children, this journey is usually paid for by the parents as their children go wandering around for a summer. It helped established the International Banking System for transferring funds, expanded the ability to send messages via various communication networks, and encouraged lavish parties in tourist destinations.
For the poorer socioeconomic classes, the mandate trip is a community effort where every four years, entire schools travel across the country with little more than going to a distance location, spending a night or three, and then come back.
Influence
It is questionable if the goals were ever succeeded.
For the rich, they would bring their own friends and had little reason to interact with anyone at resorts and exclusive locations. The only outside influence was different tastes and dishes to enjoy, lovers that would be forgotten soon after, and the occasional trinket.
Likewise, the poorer teenagers spend most of their time traveling, have little money, and can experience less. On the other hand, because of the time and distance, they do encounter a wider range of others as they slowly plod across the country.
