The first of the international conventions on the carriage of goods by sea was the Hague Rules of 1924. In 1968, the Hague Rules were updated to become the Hague-Visby Rules, but the changes were modest. The convention still covered only "tackle to tackle" carriage contracts, with no provision for multimodal transport. The industry-changing phenomenon of containerization was barely acknowledged.[3][4] The 1978 Hamburg Rules were introduced to provide a framework that was both more modern, and less biased in favour of ship-operators. Although the Hamburg Rules were readily adopted by developing countries, they were shunned by richer countries who stuck with Hague and Hague-Visby. It had been expected that a Hague/Hamburg compromise might arise, but instead the more extensive Rotterdam Rules appeared.
