elected two MPs. By the time of the 1831 general election, out of 406 elected members, 152 were chosen by fewer than 100 voters each, and 88 by fewer than fifty voters. By the early 19th century moves were made towards reform, with eventual success when the Reform Act 1832 abolished the rotten boroughs and redistributed representation in Parliament to new major population centres. The Ballot Act 1872 introduced the secret ballot, which greatly hindered patrons from controlling elections by preventing them from knowing how an elector had voted. At the same time, the practice of paying or entertaining voters ("treating") was outlawed, and election expenses fell dramatically. Rotten boroughs The term rotten borough came into use in the 18th century; it meant a parliamentary borough with a tiny electorate, so small that voters were susceptible to control in a variety of ways, as it had declined in population and importance since its early days. The word rotten had the connotation of corruption as well as long-term decline. In such boroughs most or all of the few electors could not vote as they pleased, due to the lack of a secret ballot and their dependency on the "owner" of the borough. Only rarely were the views or personal character of a candidate taken into consideration, except by the minority of voters who were not beholden to a particular interest. Typically, rotten boroughs had gained their representation in Parliament when they were more flourishing centres, but the borough's boundaries had never been updated, or else they had become depopulated or even deserted over the centuries. Some had once been important places or had played a major role in England's history, but had fallen into insignificance as for example when industry moved away. For example, in the 12th century Old Sarum had been a busy cathedral city, reliant on the wealth expended by its own Sarum Cathedral within its city precincts, but it was abandoned when the cathedral was moved to create the present Salisbury Cathedral, built on a new site nearby ("New Sarum"). The new site immediately attracted merchants and workers who built up a new town around it. Despite this dramatic loss of population, the constituency of Old Sarum retained its right to elect two MPs, effectively putting it in control of a single landowning family. Many such rotten boroughs were controlled by landowners and peers who might give the
