Why is "Convention of Royal Burghs" trending?

Wikipedia Overview

The Convention of Royal Burghs, more fully termed the Convention of the Royal Burghs of Scotland, was a representative assembly which protected the privileges and pursued the interests of Scotland's principal trading towns, the royal burghs, from the middle of the 15th century to the second half of the 20th century. It evolved as a forum in which burgh delegates, termed "commissioners", could "consult together and take common action in matters concerning their common welfare" before and during the sittings of parliament. An exclusively merchant body, it was essentially a parliament which "declared the law of the burghs" just as the Scottish Parliament "declared the law of the land". The Convention expanded over time by admitting lesser burghs to its membership; and by the 16th century had grown in influence to the extent that "it was listened to rather than directed by the government". Though still known as the "convention of royal burghs", it referred to itself from the late 17th century onwards as simply the "convention of burghs", as by then membership was no longer restricted exclusively to royal burghs and commissioners from all types of burgh were represented in parliament.
