After the Battle of Lodi in May 1796, Napoleon Bonaparte continued to sort out two states: one toward the south of the Po River, the Cispadane Republic, and one toward the north, the Transpadane Republic. On 19 May 1797, Napoleon exchanged the domains of the previous Duchy of Modena to Transpadania and, on 12 Messidor (29 June), he proclaimed the introduction of the Cisalpine Republic, making a Directory for the republic and delegating its priests. France distributed the constitution of the new republic on 20 Messidor (7 July), setting up the division of the region into eleven offices: Adda (Lodi), Alpi Apuane (Massa), Crostolo (Reggio), Lario (Como), Montagna (Lecco), Olona (Milan), Panaro (Modena), Po (Cremona), Serio (Bergamo), Ticino (Pavia), and Verbano (Varese).
Whatever remains of Cispadania was converged into the Cisalpine Republic on 27 July, with the capital of the bound together state being Milan. On 1 Brumaire (22 October), Bonaparte reported the association of Valtelline with the republic, after its severance from the Swiss Three Gray Leagues. Austria recognized the new substance in the Treaty of Campoformio of 17 October, picking up in return what survived of the Venetian Republic. On 25 Brumaire (15 November), the full global acknowledgment and legitimateness of the new state was approved by the law administering the last addition of the vanquished regions.
The parliament, made out of two chambers (the Great Council and the Council of the Seniors), was selected specifically by Napoleon on 1 Frimaire (21 November). He advocated this undemocratic activity as a need of war. New divisions joined the eleven unique ones and Valtelline in the next months: Benaco (Desenzano) on 11 Ventose (1 March 1798), Mella (Brescia) on 13 Floreal (2 May), Mincio (Mantua) on 7 Prairial (26 May), and five branches of Emilia. The basic period of the republic was ended on 14 Fructidor (31 August), when France rejected every one of the specialists of the republic, supplanting them by a more grounded official power under another constitution.
The Cisalpine Republic was for a long time under the territory of the House of Austria.
The French Republic succeeded it by right of success. It presently revokes this right, and the Cisalpine Republic is free and autonomous. Perceived by France and by the Emperor, it will before long be similarly recognized by whatever is left of Europe.
The Executive Directory of the French Republic, not content with utilizing its impact, and the triumphs of the republican armed forces, to anchor the political presence of the Cisalpine Republic, broadens its consideration even more; and persuaded that, if freedom be the first of favors, the unrest which goes to it is the best of wrongs, it has given to the Cisalpine individuals their exceptional Constitution, coming about because of the knowledge of the most edified country.
From a military administration the Cisalpine individuals go to a protected one.
That this change should encounter no stun, nor be presented to turmoil, the Executive Directory however legitimate to choose, for the present, the individuals from the administration and the authoritative body, with the goal that the general population should, after the pass of one year, have the race to the empty spots, in adjustment to the Constitution.
For an incredible number of years there existed no republic in Italy. The hallowed fire of freedom was doused, and the best piece of Europe was under the burden of outsiders. It has a place with the Cisalpine Republic to show to the world by its astuteness, its vitality, and the great association of its armed forces, that cutting edge Italy isn’t worsened, is as yet deserving of freedom.
