The rise of the Rothschild family essentially originated from the chaos brought to Europe by the Napoleonic Wars. It is the only multinational trust network in Europe with a good record of rapid money movement. Here are three key terms: trust network, rapid movement, good record. 1) The larger the trust network, the richer the different resources you can connect and exchange from different regions. If you have resources that other networks do not, then you are certainly more valuable. 2) Rapid movement means that transfers that take others months or days can be completed in just a few hours or seconds, which can determine victory or defeat at critical moments. In a confrontation between two armies, one side can obtain new resources through a sophisticated trust network, pay soldiers on time, and maintain ample supplies, boosting morale; while the other side, with a low-level and slow network, may exhaust local resources, leading to soldiers slacking off or even rebelling, with external support arriving late, quickly resulting in chaos. 3) A long-term good record. Some trust networks may seem fine in the short term, very convenient and cheap. But when trouble arises, the network collapses, and partners or central nodes suddenly act untrustworthy, turning against you or disappearing completely. The harmed party lacks effective means to protect their rights. Such networks quickly decay, giving way to those with better records. The decline of the Rothschild family's position in the international financial system essentially stems from the rise of telegraph technology after 1843 and its widespread adoption in the financial industry. The new network built by telegraph technology gradually challenged and surpassed the traditional network based on the Rothschild family's private messengers.
