Because the Kingdom of Altland has no written constitution, it also has no single, unified, and systematic "bill of rights." This should by no means suggest, however, that certain fundamental human rights of its inhabitants remain unrecognized or unprotected. Indeed, a network of statutes, customs (which in Altland acquire the force of law after seventy years of continuous practice), and numerous sayings in the Book of Precepts all lay down certain legally inviolable rights, some of which are recognized as accruing to all people in virtue of their human nature, and others of which are seen as possessed in virtue of their citizenship in a particular nation (i.e., "civil rights" strtictly so called). Among the former is the right to freedom of religion and conscience, which is not only recognized by the state, but which has also been vigorously upheld by the theologians and religious teachers of all three of the important religions of the realm on the basis of the very nature of an act of religion, which, though external, must proceed from sincerity of heart. Therefore, in Altland, conscience is never coerced, nor is any specific religious act ever required of anyone who has not already solemnly made a free and personal profession of the religion of which it is a part. In short, all religions professed and practiced within the nation are respected and encouraged.

        Cruisianity, embodied in the Church of Altland, is the official state religion of the kingdom, and the actual professed religion of about 85% of its inhabitants. It is a hierarchically structured church divided into four ecclesiastical provinces (Midlburgh/Komdn, Sigesburgh, Flores, and Calopia) headed by archbishops, each comprising five bishoprics. The bishops claim apostolic succession. The direct successors of the first bishop in Altland, once the bishops of Komdn, now the Archbishops of Midleburgh, exercise the primacy. Monastic and quasi-monastic orders of men and woman play a important role in the life of the Church. As the official religion of the sovereign and the actual religion of the vast majority of the population, it enjoys the protection and patronage of the royal and provincial governments and plays a prominent role in the national public life, as well as in the private lives of its adherents. Its cultural and charitable works are subsidized by the King and the nobility, and its courts have jurisdiction over members of its clergy, over those who dwell or conduct business on its properties, and over the marital and family affairs of its adherents in so far as these would otherwise come within the purview of the civil law.

Roughly ten percent of the population of Altland practices a form of Cruisianity which first appeared four hundred years ago in among the Romança-speaking people of Sperança and later gained adherents in Montemar, Altasilva and western Orlandia. Called Reformed Cruisianity, it emphasizes salvation by faith alone, the private interpretation of the Scriptures as the sole source of religious truth, and the completely unmerited imputation of righteousness to a divinely predestined minority of mankind. Their ecclesiastical structure is non-hierarchical and their worship for the most part non-ritualistic. Although in its early days, the nature of these beliefs promoted the development of numerous self-contained and mutually antagonistic religious groups, these have, over the past century, drawn together into an inclusive organization called "The National Convention of the Reformed Churches of Altland." Now legally recognized and under the patronage of the Crown, this organization functions for its members in much the same way as The Church of Altland does for its, and a tribunal composed of clergy representing all shades of theological opinion functions as the legally recognized ecclesiastical court for those professing Reformed Cruisianity. Reformed Cruisians are to be found today throughout the country, but concentrated mainly in its cities, with particularly large numbers of adherents in Cita Sperança (Sper.), Midleburgh (Jer.), Montmayor (Mon.), and Ernestina (Alt.),

Over the course of the centuries, there has emerged, particularly in Cita Sperança and other cities of the Eastern Coast, a small minority of Altlanders who profess and follow an ancient religion which preceded Cruisianity, The Religion of the Covenant. In Altland these believers are known as "Federists."Royal decrees guaranteeing the free and open practice of their religion were first introduced more than two hundred years ago by the then King of Romandia in response to scattered attempts by Cruisian authorities to suppress it. These decrees were extended to the entire country upon the achievement of national unification early in this century, and an organization called "The Rabbinical Council of Altlandic Federism" was established on the same legal footing as The Church of Altland and the National Convention of the Reformed Churches of Altland. The Council choses the Chief Rabbi of Altland, who normally then becomes leader of the Grand Synagogue in Cita Sperança, which has the largest Federist community. However, since the extension of the Romandian toleration decress to the whole country, a significant Federist community has also grown up in the national capital and its suburbs.

Another belief system which came to the tolerant shores of Romandia in the obscure past and has established itself there among a tiny community in the hills of the current province of Sperança is The Sevenfold Path of the Enlightened One, commonly referred to as Nirvanism. The Nirvanists maintain one large temple in the the province's second-largest city, Polita, and several small ones in neighboring communities. The large temple in Polita has a monastery attached which houses about fifty monks, together with a convent for a similar number of nuns. Two smaller monastic communities exist in other places nearby.

The most recent religion to establish itself in the Kingdom of Altland, the Religion of Moún, has come only recently from the Island Nation of Djeriga and, attracted by the tolerant culture of the Romandian provinces, built am impressive place of worship in the southern suburbs of Cita Sperança. Currently, most of the adherents of this creed are Djerigans, recent immigrants from Afrazure Altlandique, and other foreign nationals from countries to which the religion has recently spread. A small mosque, built by the Djerigan government for its diplomats, has also opened recently in Midlburgh.
