During almost the whole of his reign the Danes were engaged in a political struggle between the "Right" and the "Left," the party of order and the party of progress, the former being supported in general by the Landsting, and the latter by the Folketing.
(1340), who for nine years had held Jutland and Funen and dominated the rest of Denmark, first opened Valdemar's way to the throne, and on midsummer day 1340 he was elected king at a Landsting held at Viborg, after consenting to espouse Helveg, the sister of his most important confederate, Valdemar, duke of Schleswig.
In 1349, at the Landsting of Ringsted, Valdemar proudly rendered an account of his stewardship to the Estates of Zealand, and the bishop of Roskilde congratulated him on having so miraculously delivered his people from foreign thraldom.
The constitutional rescript of the 28th of January 1848 had been withdrawn in favour of an electoral law for a national assembly, of whose 152 members 38 were to be nominated by the king and to form an Upper House (Landsting), while the remainder were to be elected by the people and to form a popular chamber (Folketing).
The salient feature of Danish politics during subsequent years was the struggle between the two Tings, the Folketing or Lower House, and the Landsting, or Upper House of the Rigsdag.
Nevertheless, the ministry, supported by the Landsting, refused to resign; and the crisis became acute when, in 1875, J.
Perceiving that the coming struggle would be essentially a financial one, he retained the ministry of finance in his own hands; and, strong in the support of the king, the Landsting, and a considerable minority in the country itself, he devoted himself to the double task of establishing the political parity of the Landsting with the Folketing and strengthening the national armaments, so that, in the event of a war between the European great powers, Denmark might be able to defend her neutrality.
In 1886 the Left, having no constitutional means of dismissing the Estrup ministry, resorted for the first time to negotiations; but it was not till the 1st of April 1894 that the majority of the Folketing could arrive at an agreement with the government and the Landsting as to a budget which should be retrospective and sanction the employment of the funds so irregularly obtained for military expenditure.
In spite of the composition of 1894, the animosity between Folketing and Landsting continues to characterize Danish politics, and the situation has been complicated by the division of both Right and Left into widely divergent groups.
The session of 1896-1897 was remarkable for a rapprochement between the ministry and the " Left Reform Party," caused by the secessions of the " Young Right," which led to an unprecedented event in Danish politics - the voting of the budget by the Radical Folketing and its rejection by the Conservative Landsting in May 1897; whereupon the ministry resigned in favour of the moderate Conservative Herring cabinet, which induced the Upper House to pass the budget.
Moltke continued to take part in public life as a member of the Landsting, or Upper House, but henceforth kept in the background.
