However, at the time, secession required either a majority vote from the state legislature or a successful referendum. Because the official state government refused to ratify the document, Kentucky remained a part of the union. But, as demonstrated by the Russellville ordinance, the ties were tenuous: the Unionist majority in the state senate was small, and to protect the status of the state, the Unionists created and passed a bill that declared Kentucky a neutral party. This position led to the labelling of Kentucky as a border state in the Civil War, and made the retaining of Kentucky a high priority for the Union.
