In a pre-mechanical and pre-electronic world, communication was by land and sea couriers. It therefore established river and sea transport for those cities near water, and for the others, post-houses which held relays of horses for couriers to use carrying messages. Of course these transportation routes also carried commercial and military traffic.
Samuel F.B. Morse's invention of the telegraph revolutionized communication by enabling near-instantaneous transmission of messages over long distances. This drastically reduced the time required to convey information, allowing for real-time communication between cities and countries. It transformed industries, facilitated faster business transactions, and enhanced coordination in various sectors, including transportation and military operations. Ultimately, the telegraph laid the groundwork for modern communication technologies.
Morse code revolutionized American communication by enabling rapid long-distance messaging, facilitating the growth of the telegraph system, which connected cities and remote areas. It played a critical role in industries such as railroads and shipping, enhancing coordination and safety. Additionally, Morse code fostered a sense of national unity by linking disparate communities, allowing for more immediate news dissemination and information sharing. Overall, it laid the groundwork for the modern communication systems that followed.

A large enough body from space (comet, asteroid, meteor) that did not break up when coming through the Earth's atmosphere; a large sun flare or coronal blast; and a nuclear weapon detonation all have the ability to destroy entire cities and impair electronic communication systems.
Electromagnetic pulses (EMPs) can destroy entire cities and impair electronic communication systems. These bursts of electromagnetic energy can result from nuclear explosions at high altitudes, as well as from certain solar events, potentially disabling or damaging electrical grids and electronic devices over vast areas. The disruption can lead to widespread chaos, affecting everything from transportation to emergency services.
