After the displacement of the indigenous population in the place by the entrance of the conquistadors, the lands would remain in the power of the State who would then transfer it to private hands and colonization companies by various means, either by payment for services, reward or collaboration to the government, being in this case, also repaid for the campaign organized to eradicate the “Indian” tribes of some areas of the province of Santa Fe.

Between 1864 and 1867 the Province of Santa Fe had contracted a loan with Mariano Cabal for being a supplier of supplies and food to the Argentine Army in the Paraguay War (1865–70).

Of which he would later sell to Lehmann and Cristian Claus on April 30, 1875, one hundred concessions numbered from 1 to 100....‘’In the new Colony called Pilar, recently founded on the part of the land that, situated in this Province and Department of the Capital in the place called ‘Las prusianas’, composed of twelve square leagues, bordered on the north by Mr. Cullen and others; on the south by Messrs. Beck and Herzog; on the east by the fields occupied by Don Carlos H. Seguí, of the will of Elía; and on the west with fiscal land”.

As it happened in numerous cases in the province, the settlement of the colony of Pilar began without the formality of a founding act....“In the absence or non-existence of the Act of Foundation of a town or Colony, the General Archive of the Province holds the criterion of determining, in its replacement, another fact that possesses a similar meaning.

That is to say, the act as a result of which the existence of such community is originated or set in motion” ...[9]In this way it is considered that the purchase of land made on April 30, 1875 by Guillermo Lehmann y Claus to Agustín Cabal, would be the act where the establishment of the colony is set in motion, because from that moment the settlers began to settle in the place; the verification of this execution can be verified in the report of January 1, 1876 in which the Inspector of Don Jonás Larguía, informs that eighteen concessions were sold in which twelve families were installed.
