Prazo

Prazo is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Prazo rather than just read about it. In short: A prazo (or prazo da coroa) in Portuguese Africa was a large estate leased to colonists, settlers and traders to exploit the continent's resources. Prazos operated like semi-feudal entities and were most commonly established in the Zambezi River valley.

Key takeaways

  • Prazo belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Prazo to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Prazo from memory before moving on to harder problems.

Reference excerpt

A prazo (or prazo da coroa) in Portuguese Africa was a large estate leased to colonists, settlers and traders to exploit the continent's resources. Prazos operated like semi-feudal entities and were most commonly established in the Zambezi River valley.

Definition The prazo was a land grant/lease given in exchange for an annual fixed fee based on laws promulgated by Portuguese kings, such as Afonso V and Manuel I.

History The existence of the prazos as an institution has been known since the 16th century, but the terms prazo and prazeiro ("prazo owner") only appear in sources from the 18th century onwards, with the estate and their owner before then being called foro and foreiro, respectively. The leaseholder was required to live on the granted land and could not sell or rent it, although lessees frequently violated that rule. In Tete Province during the 19th century, 32 prazeiros owned 57 prazos. The land grant was not supposed to exceed 500 leagues in length, although most did. In 1677 a system was adopted to attract Portuguese settlers. Vacant prazos were to be granted to "deserving orphan girls or the daughters of crown servants", who would pass the prazo on to her eldest daughter for three generations who married to Portuguese men. At that time the government could retake control or renew the lease. The prazeiro was allowed to employ Africans (colonos); to raise a private army (often made up of slaves); trade in all commodities; and maintain law and order. The Portuguese Crown intended the prazo to guarantee control over the land, stimulate agricultural production, facilitate European settlement, and be a source of revenue for the government, but the system failed in the objectives. Contributions to the failure were rampant absenteeism, violent rivalries between the grantees, the scarcity of Portuguese women, lack of capital, and Africans, of which the latter cause was probably the most important. The prazo system's concepts of female inheritance, three lives, and individual landownership were alien to African traditions. In the 19th century, Portugal often failed to maintain centralized control over the prazos, which shifted between a loyal and a dissident stance towards the Portuguese Crown. For example, one Mozambican prazo was transformed into the anti-Portuguese Macanga Kingdom under the ruler Choutama (Pedro Caetano Pereira) and his son and successor Chissaka. The government failed in an attempt to reform the system in the mid-19th century. Another attempt was made in the 1890s without result, but the introduction of the concessionaire companies about that time, the 1890 British Ultimatum and the Portuguese Colonial Act of 1930 contributed to the end of the prazo.

Worked examples

Example 1 — a first encounter with Prazo

Start with the simplest possible case. Write down what Prazo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Prazo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Prazo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Prazo

In research
Prazo appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Prazo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Prazo is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture in Africa, History of Portuguese Mozambique, so understanding it makes those chapters shorter.
In everyday life
Look for Prazo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Prazo in simple terms?

A prazo (or prazo da coroa) in Portuguese Africa was a large estate leased to colonists, settlers and traders to exploit the continent's resources. Prazos operated like semi-feudal entities and were most commonly established in the Zambezi River valley.

Why does Prazo matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Prazo?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
